- This is a typical Tecumseh snowblower carb.
NEW CARB for under $20 amzn.to/1Qaefc6 in recent years China has released these carbs. I do think the original carb that is cleaned will work better, but these are a decent alternative if you don't want to tackle the cleaning.

Thank you SO much for your excellent videos. I haven't been able to use my ancient Sears Craftsman snow blower for the past couple of years because it just wouldn't run. I am a 61-year-old female who didn't even know what a carburetor looked like or where it was. After watching your videos, I was able to remove and clean the carburetor and my snow blower is now running again. I couldn't have done it without you :)
This^ Best comment I have read in a long long time. With all the crap you see and how commercialized the platform has become, it's comments like these that remind us why most of us came here in the first place. Not to laugh at others expense. Not to troll , bully , shill or to get likes. We came for help. Either to get help with everyday problems or help others with theirs. People wanting to help each other. Thank you so much for your comment Ms.D. It made my day. Kindest Regards
I applaud you for taking the time to learn how things work and then doing the job yourself. You learned something new and now have the skills to check and fix again :) It's moments like this that make the community stand out. Good job.
Sixtyfiveford...I TRULY cant thank you enough for doing this video. My pops had very similar model and never...EVER...did tune up and the night before a big snow storm we asked him did you check to see if it works, his reply " it starts up every year, so its fine"...Im sure by now you see where this is going. Wake up next morning to him stressed out cause it will not start. So I had a little fun with him first and broke his balls about not checking it and etc etc, then broke his balls about not having a smart phone, which if he did he could youtube some videos. Just when I was about to see steam coming out of his ears...I took out my Note5 phone, searched and found your video...did everything you showed and it started right up. Again, I really cant thank you enough for putting this video up! YOUR THE BEST
I've cleaned carbs for years on small engines, never really had much knowledge of how they work, just made sure all the holes were clean and everything moved again that was supposed to move. Thought I'd see what I could find on UA-cam for a video on the subject. I appreciated your explanation of the working of the carburetor as well as older versus newer models. You obviously have a great working knowledge of carburetors and you shared a lot of excellent information and didn't waste any time doing it. Sincere thanks!
Dude I watched your video to prepare myself to do that exact job and I’ve also watched about five other ones and I want to tell you that you were the only one to mention that there’s no air filter on a snowblower. That’s awesome because I haven’t taken it apart yet and nobody yet has mentioned that in any video that I’ve watched so thank you very much for the quick and detailed explanation.
Thanks, I'm glad it was helpful.
True, snowblowers have no air filters. I am repurposing my snowblower engine for a summer use horizontal sawmill so have had to makeshift an air filter. It was a Briggs engine and I did manage to attach the air filter. It did require some mods but it works just fine.
Yeah, I couldn't find it.🤣
I tried out this "trick" as we got dumped with some really wet snow on Friday. I had some 7 ply conveyor belt that I used to modify it with and it worked perfectly. Usually I would have to shovel this type of snow, which really sucks because the heavy stuff is what you want a snow blower for. It worked so much better that we my neighbor asked what I did and we fixed his snow blower up this way as well. Thanks so much you saved my back a lot of pain.
Yo! Henry from Long Island NY here! I got a Lawn Boy 5/24..looks just like your blower in the video, with identical carb! It started but ran like crap, bogged out, and only ran while in full choke. I took off the carb and the bowl was full of gunk! I need to go out and get a new bottle of carb cleaner to do the rest, but I have to tell you that I love your videos! Very informative and you do a superb job! Ill post back and let you know how it came out!
Great set of videos got me back up and running day before a snowstorm with no stores stocking any new snowblowers life saver thanks
Hey Thanks.
Thank you for this video! I have never worked on engines before but the idea of spending $200 to have someone repair a $600 snowblower just didn't make sense to me. My MTD yard-machine snow-blower just refused to start. I followed all your steps one by one and while doing so I wasn't convinced it was going to work for me because the carb was awfully clean inside and out. But sure enough after putting everything back together, she runs like new! If you were neighbor, i would buy you a beer!
thanks again!
That's great. I'm glad you tried the repair yourself.
Thanks SFF: I bought mine at a garage sale for $50 and a few carb choke bits were missing - this nicely detailed video resolved so many questions. Thanks
I already took the carb apart and cleaned it the best I knew but missed that small hole on the main jet. This video is perfect. Thanks!!
Glad it helped
Thanks for the video !!!! My snowthrower is having the exact problems you described in the first video ( choke has to be fully on for it to run ) so now I know how to clean the carb. Now to get outside in the cold and do it.
Calvin Lee Your main jet is clogged and it may be something simple like I show in this "Quick" version. ua-cam.com/video/KYj5oH0vNVg/v-deo.html
sixtyfiveford
I did the "quick" version just about an hour ago . I put everything back together and wahla it started right up on the third pull !!!! I have NEVER been able to start it up by hand before. I always had to use the electric start and that's a pain in the butt when I'm out at the road. THANKS SO VERY MUCH FOR THE VIDEO !!!!!!!!!
I've done this many times! Just wanted to see how others do it.. Very well explained and shown my friend! Its a nice thing you're doing showing others how to service small engine's. God bless you brother!
Thanks.
Fantastic information for my old, 18 year old snow blower. Followed your rebuilt tips and runs perfect again. Mine has the "newer" non adjustable carb.
Glad it helped
My 5.5 Horsepower Craftsman snowthrower after two years of sitting was completely without a pulse, so I followed the corrective action as detailed in this very informative video. To-day with new life the beast stands ready to defend the honor of my driveway......first class help to us all out there....thanks sixtyfiveford. BTW I was unable to effectively use the inlet needle to
place the seat in it's required position. When placing the seat in position the contact (pointed) end of the needle only served to expand the seat in the tunnel resulting in a jam. After some light lubrication and the use of a suitably sized drill shank placed over the seal I was able to eventually apply pressure and guide it into place. Many thanks my Craftsman now works as new.
I'm glad it's up and going.
I have this exact tecumseh motor on my snow blower. It would not run right so I am cleaning and replacing the gaskets/o-rings/seats on the carb. Your video came in very handy! Thanks!
I am fixing my tecumseh snow blower (ariens) carb now, first time working on a carb thanks for the vid!
Your are very talented at your craft. Very detailed orientation and precision is immaculate. " 2 primes " without a doubt start up. Flawless Victory.
I like the no nonsense way you did this. And nice job of showing how to fix the carburetor. Thanks!
Thanks. I hope it helped.
Awesome. Thanks. Just took apart and cleaned mine in prep for winter. Last winter it was surging and stalling frequently. Cleaned it all out and it runs smooth, even at low idle. Hope this did the trick, but when winter comes, I'll know for sure.
Thanks, I'm glad you liked it.
I want to thank you so much for this video.
Im moving where I no longer need a snow blower and I
wanted to sell mine. When I pressed the primer bulb,
gas would leak out on to the tire.
I thought it was the primer hose, so I replaced that, but
the problem was still there. I then bought a kit to
replace the needle valve and the main issue, which
I felt was the cup washer. My little clip for the needle
valve was very loose and not what I would have wanted,
and the pin that holds the float pops out like nothing if
you put the snow blower on its blade cover/upright.
When I press the bulb now, I do not get the feeling
that Im getting pressure, but when I put it together
and pressed the bulb 10 times, it started right up
and keeps running like a champ.
Thank You so much for your help with this video !!!
ctguy1955 That's great. Sounds nice to move somewhere where snowblowers are no longer needed.
I am very aware of the dangers and appreciate the concern. I'm in a very well ventilated area with a fan blowing across me and I'm wearing gloves? There are no safer chemicals for cleaning carbs that I have ever seen.
A+ Video! My Craftman snow blower constantly idles up and down and seems to lack power. I'm going to follow this video...Cant' wait!
Great lesson to learn on cleaning the carburetor.I might need to watch twice ,in order to remember every single step.thanks so much for a such a helpful video.
Nick Muresan
nick muresan Thanks. I also have a quick version of this video where I address the main problem of these not running good. ua-cam.com/video/KYj5oH0vNVg/v-deo.html
Nice detailed video, My craftsman snow blower with the motor like yours, it keeps idling up and down while in motion and at a stand still; it seems to lack power. I'm going to see if I can clean it myself. I'm suprised by the amount of carb cleaner you use, I can almost smell it by watching this video lol.
Great instructions it helped a lot. Got my snow blower running all because of your video.
+leathers76 Awesome.. Glad it helped.
Great videos. I just rebuilt the carb on my 8hp tecum.... subbed your channel..very informative and you explain everything needed to do.I like that you dont rush through the process.
Thanks again
D Lastname Thanks.
Great video set. I don't have to clean mine yet, but will definitely come back to rewatch!!!
I have a 5 minute quick clean video on these carbs that solves most issues.
@@sixtyfiveford I have a 2 Stroke Single Stage (Atlas) that will start if you give it enough starting fluid. Assuming bad gas and gummed up carb. If I blow this one up, I have a 28" Dual that's my primary. Would like to get it reliable and use it or sell it.
@@jbpoplockanddropit Try a quick clean and you should be done ua-cam.com/video/KYj5oH0vNVg/v-deo.html
Many , many thanks to you , got her running like a champ ! Couldn't have done it without you!
+spuyten duyvil Awesome. Glad it helped.
Same here ... really helpful ... I am so happy I think I will do the neighbors driveway too. Thanks a lot!!
Thanks. The surging is generally a clog in the idle circuit. Yes I use a fair amount to keep it clean. The use of spray carb cleaner vs compressed air lets you physically see if a passage is open or clogged. Let me know how you fair.
Thank you for taking the time to post this video. You made my day a lot easier... Keep up the great work.
+Derek Derouin That's great. I'm glad it helped.
Thanks for the good step-by-step video. My problems vanished. It was the main jet and the emulsifier tube holes causing the erratic idle and high speed power drop-offs. I owe you an "adult beverage", at the very least.
+John Panyon Great.. I'm glad it helped.
good video I bought an 8hp model like this one for next to nothing and it was backfiring pretty bad cleaned the carb out and found I had rust in the bowl it came from the welch plug and my low speed needle was rusted as well. I scraped all the rust off the welch plug cleaned all the passages and installed the new parts, it runs like new now.
davidbrennan5 Awesome. They'll run forever, they just hate gas being left in them. Drain and run it out of gas and it will start every season for you.
sixtyfiveford Thanks again for anyone who wants to know I bought the genuine Tecumseh carb kit for 15.00 from a local small engine shop, it comes with a new needle/seat/spring new lowspeed needle and oring new highspeed jet/needle oring and gasket new float pin new welch plugs and a new float bowl gasket.
Awesome explanation thanks! Fixed my neighbors snow blower they were going to throw it out because they could not get it to start I knew as soon as I pulled the plug and it was black as spades that there was also going to be carb issues because they did not winterize it ever lol.
You're welcome. I'm glad it helped.
I finished, did both snow blowers. Both machines I had to replace the float valve seat, only realizing it after putting it together and no gas would flow into the bowl. Also, the machine that is newer and run only a few times about 10 years ago had more gunk than the old machine that I used last year. I swear the newer machine must have had linseed oil run through it. It smelled like varnish and was sticky, I couldn't believe it. Used 3 cans of carb cleaner between the 2 machines.
Probably the best how to video I have seen. Thank you!
Thanks, I'm glad you liked it
Awesome Henry. It's amazing what this old gas turns into. Make sure you get all the little holes in the main jet and it should run like new. For sure, let me know how it goes. -Moe
Thank you so much, this is great! You should be a spokesman for carb cleaner the way you use that stuff!! lol
+TerryG Yeah, if you want a clean carb you'll need to flush away all the contaminants.
You're welcome. Now you have a Super Snow Blower. Have a great rest of the winter.
Great video! very clear and perfect instructions. I have the same exact snow blower and it's running fine. However I just bought it from someone and will be using your video to put my carb in tiptop condition. Thanks !
+Victor Jinete Great, glad the video can help.
Awesome video! Thanks for the post it really helped me take my old carb off and instead of rebuilding/cleaning I just replaced it. I replaced it with one that doesn't have the screws on the bottom to regulate it. My question is after that I was unable to start my snowblower. I've check my spark plug and ignition coil and both give spark. Am I missing something? Also, the right of of the there is this bolt and above is a diagram for on/off; I have the bolt total tightened.. is that correct?
Any information will be much appreciated.
I cleaned the carb according to very easy instructions and engine now starts, and will run. My problem is that here is a small, and I mean really small pinhole on the carb body above and between the primer inlet and the 2nd adjustable needle valve that spits out fuel while the engine runs. Is there a plugged air passage in there somewhere?
Question: Why does the snowblower backfire when I try starting it ? It is an old 10 HP Ariens snowblower with a Tecumseh engine. Thanks in advance.
Can't tell you much I appreciate both of your videos - a great help and the driveway is clear! Thanks very much, Merry Christmas, and a fabulous 2015 to you-
Churchill Barton Thanks.. Have a Merry Christmas yourself.
I was VERY close to buying a new carb but in the end it was just a dirty carb. Though I will say I overlooked changing the fuel line
Needless to say my $20 snowblower is working awesome, I have a better understanding of 2 stroke engines and carbs, and I am almost looking forward to snow.
Glad you got it sorted out.
THANK YOU! What if you have the NEWER style, with the shorter screw. will that screw have 'holes' in it that need to be cleaned liked you've shown?
THANKS!!!
Yes, they newer style Tecumseh will have holes in the bolt.
sixtyfiveford Thanks! That is probably my problem..
Should gas be filling the float bowl even if the primer is not working or does it fill only when the engine is running? After hooking up the gas line to the carb, I thought gas would fill the float bowl but there is no gas in the bowl after re-installing the carb. Thanks.
hello, i have a quick question hopefully you can help me here, i recently bought a used snow blower made by noma and got the same tecumseh engine like yours, when i start it it runs fine until i put the choke back to off postion then it shuts down and wont stay runing, i have poured fresh gas, oil changed, new spark plug, cleaned the carb the same way u did, i just can't figure why it dies as soon as i turn the choke off,i am suspecting the springs on the speed lever any ideas?? thanks
Awesome. I'm glad I could help. Good Luck with the blizzard.
Another nice clear easy to follow video.Good job.
I check it at 7:49. I just dont talk about it as it wont change unless it has been messed with. Its a very basic setting which is to set it level with 90% of all Tecumsehs. I show how to do it in my other Tecumseh carb video. The reason your blower stalls is most likely a swollen needle seat not allowing the full travel of the float.
Awesome. It is virtually identical and everything I did to this one will apply to you 8hp model. Good Luck.
Your welcome. I have been working on my equipment and friends & family’s’ for the last 20 plus years. Wish I though of UA-cam years ago. The things I did by trial & error would not have been necessary due to guys like you who are willing to help out. I decided to start a shop from home. Are you willing to help with advice on the start up? If so do you have an email I can contact you at? Thank you.
I love fixing motors and stuff but I never took apart a carb before. If I do everythinf you said in the video am I likely to mess it up and need to have it professionaly fixed?
Simply amazing! Your videos are very informative and complete. Subbed! I have a Tecumseh engine I have to get running properly and I think after watching your videos I know what to do. Great work sir!
***** Thanks for subscribing. I'm glad you found them helpful and I hope I can keep you entertained. -Moe
My newer (11 years old) snow blower does not have a fuel cutoff valve. Should I install one? I am thinking I should put one on it.
I followed the video but now when I press the primer button, I don't get any gas into the carb. Any suggestions?
Gas should fill the float bowl at all times even with engine off.
Your float must be stuck up or your needle stuck up. You could also have a plugged fuel line. I would put my hand/mouth around the fuel tank filler gas and blow. This will pressurize the fuel tank and for the needle down if it is stuck.
Thanks for the video. My 1990's JD 524D is the exact same setup and runs no where near as good as when you fired that up. Will be tackling this soon.
saleen367 Let me know how it goes.
You're welcome. Let me know how it goes.
Your carb still has a blockage. When the choke is on air physically forces fuel into the engine. Does the main jet (holds on the carb bowl) on the the bottom of the carb have a screw coming out of it or is it only a bolt?
Thanks for both parts 1 and 2.
great added point with why there is no air cleaner.
Thanks for your concern but I've been doing this long enough to know what I'm doing.
You could have a hole in the air line that leads from the primer button to the carb or the carb bowl gasket is bad. If you push it fast 5-6 times it should start dripping gas out of the mouth of the carb.
Great video, very informative. Couple of suggestions. Getting your cleaner nozzle into some of the holes is a little easier if you slide a wire in the tube of the cleaner. If you don't want to scratch stuff to remember where it went take pics as you tear it apart. The wrench on the main jet confused me a little, the "little more than one turn" reference is to turning it in to gently seated..... regardless of what position the base is at.
Damn you made that look easy. You fix blowers for living? My blower don’t work it’s 12 years old. I’m gona clean the carb I have no idea what I’m doing.
Thanks for the time and sharing. I have a 1978 Craftmans I am trying to clean and rebuild some seals on. Why bother with a 35 year old snowblower...Cause its what I got :)
YOU ROCK!!! I was able to take my non-starting, 19 year old snow blower and get it running again - THANK YOU!! A quick question - when I got to the part about pulling the priming bulb hose off the carb - I noticed that their wasn't one! What is the best way to get to the bulb to attach a new hose and string it back through to the carb? Do I have to remove the entire cover by the recoil string? If so, I see the 3 bolts on top holding the cover - are their more? Have you happened to video this removal?
Thanks again!!
Kabauer If there is no hose at all, yes you need to remove the entire front cover. There are 3 top bolts and 2 bolts on the side/bottom. Here is a video that covers removing the front shroud for engines(I'm replacing points). Just watch the removal/ reinstall parts ua-cam.com/video/HV9MJwsUP_4/v-deo.html ua-cam.com/video/HV9MJwsUP_4/v-deo.htmlm24s
sixtyfiveford Thanks again! Unfortunately something is funky with mine. I removed the top three bolts and the one on either side. I can wiggle the entire front cover - but.... The top will slide off ~ 0.75 inches before binding. The sides each will pivot ~ 0.25 inches before binding but it is almost like the inside the bottom is hung up. I can slide a piece of paper between bottom of cover and frame so nothing is attached there. If I pry out on the left side, the right side pivots in and visa versa - but I can't get it to pull straight out. Could there be something inside the bottom of the cover that is hung up? Sorry - but this one has me stumped!
The only thing I can think of is the wire below the carb is sometimes screwed to the cover.
If you don't have an electric start there is a flap on the opposite side of the carb. It is held on with small bolts and will keep the cover from sliding off.
Very good instruction. Thanks for posting. hope what I learned here gets the Snapper goin...
Thanks Joe.
Thanks so much, man, I'm about to tackle my HSK80 carb with renewed confidence.
Excellent video.I've cleaned a couple of the fixed jet carbs in the past.They didn't run any better after being cleaned,so I had to replace them.They weren't that gummed up/dirty but they just didn't run well.Any suggestions on what I could've missed?
+clint eastwood The brass jets tarnishes with the new ethanol and water and makes the jet smaller. If after they are cleaned they still need partial choke to run smoothly the main jet can be drilled out to a slightly larger size. You can pick up a micro drill bit set for a few bucks at Harbor Freight.
Thanks for all the info. Quick question, how am when should I grease the gear box in my stage 2? I haven't looked too close, but from what I have seen, there is a bolt that you take out to add grease. Thanks!
Paul Nieves Most will take gear oil. Ones made in the past 20years are permanently lubricated and generally need nothing unless you see that they have leaked. You can add a little gear oil through the the hole to help redistribute the grease/oil already in there.
My carburetor has the spring on the pin for the float does it have to be on and how does it hook? It is on a model321 cub cadet snow blower. I really like our video very helpful !
Great job! My Toro 824 xl snow blower will only start after pouring gas into cylinder (via removed spark plug). It then fires right up and runs perfect. I've cleaned the carb numerous times and it's spotless. During the Last clean the bowl gasket broke. I glued it back together and reinstalled it. There was no change in the non starting issue and it again it runs perfectly. You mentioned the gasket can cause primer issues. It does seem like the primer is not pushing gas into carb? I did confirm that it does push air at the hose end that attaches to the carb though. Any suggestions? The machine is in excellent condition otherwise and always run with non ethanol fuel and garage kept. Thanks
If the bowl seal isn't air tight it won't prime. They primer simply pumps air into to bowl and it forces fuel up the main jet/emulsion tube into the throat of the carb.
Ok Thanks, so if i replace the seal and still have the non start issue then the only thing left would be a blockage in the main jet/ emulsion tube. I've cleaned that numerous times so betting on that seal being bad. Of course those $10 carbs on ebay may be another option as much as i'd rather stay with the OEM carb on the blower. Thanks.@@sixtyfiveford
Thanks for watching. Let me know how it goes.
Hi, I got my 5 HP Tecumseh Craftsman snow blower running properly by cleaning the old carburetor but now I get a fine spray of gasoline out of a tiny hole in the carburetor just by where the primer hose is connected.
It's common for a fine mist to come out of the throat of the carb due to worn engine valves. It won't cause any issues.
I've soldered my carbs float, works great still, trill is too cut a the smallest piece of solder instead of using straight off the spool of solder, I mean I tiny dabs worth of solder depending on your hole anyhow. . but mine works like new 3.5 Tecumseh 85 ish on the sears 5/20 isn't many left
I have a 5 HP Tecumseh Mastercraft snowblower exactly like the one you are cleaning the carb on. Mine would only run with some choke. Instead of cleaning the carb I replaced it with an adjustable carb. The engine now surges and needs choke to keep it running. What did I do wrong?
Partial choke needing to be on to run is a dirty main jet. Engine surging is a dirty idle jet circuit.
how do you know when you have to change your welch plug , mine is not cleaning too great and i put a bunch of carb cleaner on itand its not as clean as i would like it to be .Great videos Moe!!!
Look at the little tiny holes inside the carb while you spray carb cleaner. If they don't spray smoothly out of these after several attempts, then pull the welch plug. If it sprays out of all the tiny holes, don't touch the welch plug. The first few carbs I ever did I pulled the welch plug because one came in the kit. I haven't pulled a welch plug in over 10 years and haven't had a single carb I couldn't clean.
Thanks Bowzer!
it's mainly this new High-Methanol gas they're pushing now.. It attracts water like a magnet, and we all know what happens when you leave water in an aluminum pan for a day or two.. I'm rebuilding a 8-26 Yardman/MTD right now, and it looks like I might have to remove the carb and blast it clean before next year. As someone else here on y-tube said, Always shut off the fuel and run it dry before putting it away for the seasons. Otherwise, You'll have LOTS of work come next season.
HI Great Video!!! Thank you. Have you ever come across a Tecumseh engine that won't shut off? I have a MTD pro 26inch snow blower, I recently cleaned out the carb and got it running again, but it won't shut off, and i have to pull the spark plug cable off to shut it down. Any ideas?
Yeah, the kill wire loses ground and it won't shut off. It's located under the carb.
@@sixtyfiveford Thank you for the quick response, you really saved my Snow blower!!! Is that the red wire that is connected to the "kill switch"? I think i am missing a connection. I have it connected to carb cover and the kill switch. I saw in a video is supposed to be connected to the throttle too? or are you referring to something different? Thank you once again!
@@wolfmanj3 Generally there is only one wire unless the snow blower has a charging circuit for a headlight. I should be green or black. It will hook to the bottom of the throttle as well as a key switch. However I've seen a few where only hooks to the plastic key switch. A charging circuit wire will generally have a translucent cap/plug over the end of the wire.
@@sixtyfiveford Awesome Thank you! I really appreciate it! This was my first carb cleaning experience, couldn't have done it with out your video!!!
The carburetor is new. I replaced the old one yesterday. Is there an adjustment I could make to the new carb. Could the new carb be fouled already?
That's the problem with these Chinese carburetors. a lot of them aren't jetted correctly and your engine will never run right. It's possible they didn't clean it good after machining and a metal chunk blocked the passage or they never drilled the passage. I've seen both. If you can still return it I would return it and buy a different one from a different seller.
I will. Im taking it one step at a time. As you can see in my videos, I am not the sharpest tool in my shed :)
Nice videos. I have a mower with a 4.5 HP Tecumseh fixed jet. I used your video to get it to start again BUT the spring on the regulator (that connects to the little wing that is on one of the attachment bolts got stretched and so regulated idle is too low.
I can manually crank it up so I know the carb is doing its job. Is there a way to get better tension in that spring or replace it? I know that I screwed it up by having the other linkage in the wrong hole and reconnected things without taking off the cover/fuel tank etc. Love to hear your thoughts before I decide to pass thing along to Craigslist as a freebie... The machine is about 12 years old and started being very tough to start...
You can bend the spring attachment point to increase the rpms or a new spring is generally only a few dollars.
Good idea... I think I really killed the spring. I found a place that sells them for $1.53 plus shipping...
It's interesting, I got it running. I also realized that the safety bale (the thing you squeeze to allow the machine to run/start) had stretched/become loose on the frame and THIS was the reason for the lack of a start. Still, now i have the carb clean as a whistle. Again, a nice video -- crisp and clear. Thanks for taking the time to make it. By cleaning the carb "off the machine" I got the main fixed jet and the little screwed in jet cleaned. I also got the gasket to fit better so there's now no dripping. It's still tough to prime.... Cheers! Richard
Thanks a lot man and happy New Year!
sixtyfiveford You make a lot of great videos! Thanks!
I have my impeller mod ready to install. Cant' wait.
I also am having trouble with surging and only smooth running with choke half on. I tried your quick main jet clean but ran into a problem. My carb bowel has a drain screw and another screw which I assumed was a jet. Once it's apart, it was not a jet only a regular bolt mounting bowel to the tube and carb body. Any tips? I cleaned everything out I could. They make it difficult to completely remove the carb on the new Craftsman 24" 179cc. It still surges. I can actually see the throttle linkage and spring responding to the surging.
Surging is going to be a idle jet/passage issue. If you have a newer 2-3yrs old craftman it is going to have a chinese clone of a Honda. I have a video on the Honda which is going to be virtually identical. ua-cam.com/video/n_eTqL0C3gQ/v-deo.html
That looks like it. I guess I'll I have do some more tear down so I can get it off and at the idle passage. Thanks man! Thanks!!!
Let me know how it goes.
I also just spent hours in the cold cleaning this carb for the blizzard. And if it hadn't been for this video (and the 1 of 2 video), I'd be shoveling instead of running the snowblower.
One comment: I used the screw trick to remove the gasket to clean it - bad idea. It came out chewed up. You should only remove that deep set gasket with the screw as described in the video if you plan on replacing it! (The result is the float won't completely stop the gas from coming from the tank.)
Hello Sixtyfiveford...thx for posting this, thanks to you, I know a lot more about these carbs. I have a Craftsman Tecumseh 8hp and the carb was filthy with green varnish and when I took it apart, it had no valve seat so I bought a kit, cleaned it like you and put it back together as per but when I put it on the engine, gas came out of the carb. I made sure everything was put together properly. Any ideas why it's leaking? Thanks
The needle seat is leaking. This can be from several things: float not set level, bad float that fills with gas, debris in-between the seat and needle, seat put in backwards float doesn't move freely.
Thanks for the quick response, I just bought a new seat and needle. I did put it in right but pushed it down far. I didn't set the level and thought maybe there wasn't a proper seal. I will tinker with it some more, gotta get ready for another East Coast Canadian storm in a couple of days...lol Thx again.
To make sure it is going to seal while it is apart put your mouth on the fuel inlet and blow in. With the carb upside down the weight of the float by itself should 100% seal the needle and seat.
If you need to remove the seat without damaging it, use compressed air and blow in through the fuel inlet. Be prepared to catch it. Make sure the double ridges go in first away from the needle.
sixtyfiveford Finally got the carb on with no leaks (fingers crossed). Problem now, is the throttle lever doesn't want to push the throttle open enough and the engine idles too low. I kinda bent the (larger) rod when taking it off the throttle lever. Throttle is at max and I can push it further with my finger but it lets off too much. Any ideas??
Forcing it could have moved the governor arm at its hinge pint. This will throw off the RPM setting. Or the main arm could be in the wrong hole on the carb. ua-cam.com/video/bOHv3X42-wk/v-deo.html
Ford - thanks for the video! I have a question. My snow blower will start and run fine until I have to move snow/put any demand. Then it starts to choke and will sometimes stall. I can clear the snow, start back up fine but again it will stall as soon as I try to move snow. I'm assuming it is the govenor or clogged carburetor not getting enough air to meet the demand.
Rich Goss The main jet isn't supplying enough fuel to the engine. If you have an adjustable carb you can simply turn the main jet screw out 1/8 of a turn(counter clockwise). If it is a fixed jet you'll need to remove it and clean it.Fixed Jet- Non adjustable looks just like a nut on the bottom on the carbAdjustable Jet- Has a nut with a screw coming out the center.
Great videos, as always. I have an issue with a 9hp Tecumseh carb on a craftsman snowblower. Completely cleaned her all up, but now it seems I'm not getting any gas to the carb - and there's no mechanical fuel shutoff. With electric start, I don't usually prime it at all, but now even when I prime it, it just sounds like empty air blowing around - no gas. I've pushed the primer so many times now, I should be flooded - but nothing. Thoughts?
They like to air lock sometimes after you clean them and their dry. Put you mouth on the fuel tank fill and blow.
Will do. I took it back apart and also noticed the bowl gasket was pinched/bunched at each end of the float pin which created a small gap. I'll replace that, now, too.
Very strange and frustrating. I can't get any fuel to get into the carb. If i take the carb off, gas is pouring out. So there's no blockage or pinch or shutoff issue. I must have have some sort of a float/needle/seat issue?
You should be able to pull the bowl and when the float drop fuel should start dripping. If not, your needle is stuck or seat swollen from carb cleaner or ethanol gas.
Make sure the clip on the needle is around the float tab and not under.
Make sure the bowl is put on with the deepest part away from the fuel inlet.
Yep that's where I'm at as well. My guess is swollen seat.
Pulled the bowl, no gas through. Put just a little blowing air pressure on the gas tank top and gas started going through. Lifted the float, gas stopped. Dropped the float, gas started again. Took the carb off the machine again and just tried blowing air through the gas inlet - same results. As soon as I put the bowl back on again, though (in correct position), I couldn't pass hardly any air through, and when I actually tightened it into place I got nothing. I tried about 40 different positions of that bowl to make sure I wasn't imagining things but the same was true.
With the bowl off I can see the needle moving well - not getting stuck or hung up. It is installed correctly using the wire clip. But the float only needs to move the smallest amount up before I lose flow-through again. So I'm hunting for a new seat to install, tomorrow, when my supply house is closed of course. LOL.
Thanks again for your responses. Never been up against a swollen seat before so it showed my ignorance.
Hello again! Thanks for all the small carb videos. Learning a lot here. My R-Tek/Briggs Snowblower runs like a champ now thanks to your advice! However, I have an ariens with the 3HP Tecumseh engine. I just did a cleaning on the carb. I replaced the bowl gasket, the O-rings on the emulsion tube, the needle, and needle seat. There is no adjustment screw on the main jet. The 2 problems are: after getting it all back together A. even with priming, takes 4-5 pulls to start. B. It seems to run at 75% throttle instead of full throttle, once in a while it will surge to 100% but not often. Ideas? Do I have the hole on the butterfly valve in the wrong place? Did I tighten the bowl too much? Any ideas would be awesome.
----Hard to start: Generally that means the priming function isn't working right. Either there is a hole in the hose or a leaky bowl gasket. The primer button simply forces a burst of air into the carb bowl. It goes in above the fuel and the fuel is displaced and travels up the emulsion tube into the throat of the carb. This extra fuel helps it fire.
---75% Throttle: lubricate the linkage and the lever arm that controls "stop, turtle, rabbit"
Great video, I just cleaned my main jet, I think I missed the hole near the thread though, but it runs. low speed it doesn't want to idle well, but if I put it all the way up it does fine.
I'm not sure how its really supposed to run, so I probably need to clean it still. I'm guessing youre not supposed to run them at full speed the entire time?
The little hole is for the idle circuit. For the most part these run full throttle their entire life. There is really no reason to idle the engine.
Amazon wanted 8.88 + shipping on rebuild kit, 14.55 For new replacement carb + free shipping. I went with the replace carb, easy with no issues.
Yes, the Chinese carbs have flooded the internet lately. They work most of the time but generally end up falling apart after a few seasons. Save your old carb as generally no kit is needed, just a simple clean of the main jet and you're back up and going.
I have a 9 year old snowblower has a problem. Engine Tecumseh 9hp OH318SA. It starts up and runs well initially but within 10 seconds it starts to 'hunt" the RPMs go up and down every second. When I hit the heavy snow it stops hunting and runs fairly smoothly. When I lower the throttle it stalls. What do you suggest?
The idle circuit/jet is partially clogged.
Great video....Question My Tecumseh 5.0 snowblower occasionally makes popping noises while running. Any idea what can cause this
+jdacdt Running too lean or a sticking exhaust valve is usually the culprit. If it is an adjustable jet carb simply screw the main jet out a little (1/8 of a turn) and you should be good. If this does nothing it is more than likely the valve and I wouldn't worry about it as it will run forever like this.
