I have an Areins ST724 that has the same carb. I couldn't figure out how to assemble after taking it off so my son could clean it. Your video solved the adjustment problem and was awesome in helping me to get it back on the engine.
That's a great video!
Our snowblower sat outdoors, partly covered for a number of years (at least 10) and with fresh gas did start and run for a few moments briefly this fall, but then wouldn't start at all.
I got a rebuild kit and new float and followed the video instructions and it started, and ran, on the the first try; and restarted easily.
So thank you very much for the excellent presentation. It was clear, and I especially appreciated the close-ups showing exactly what goes where. Also appreciated your explaining that drill bits could be used if the special tool wasn't available--it wasn't.
Just did this on a 1978 Ariens with a H70 Tecumseh. Your video was a great help. After the rebuild and replacing the float because there was gas inside it, the old beast is running like a champ. Thanks for such a detailed, easy to follow video!
Thank you so much for making this video! Excellent job of walking us through the process. I have a 1978 Ariens snowblower - 5hp Tecumseh engine with the exact same carburetor. I have never worked on a carburetor. Thanks to your video not only did a I take it off, throw a kit in it, and re-assemble it. It fired-up on the third pull!!! It don't leak or anything. Again Thank you.
Thanks for the clear set of instructions. Our tired old snow blower runs like a new machine. We bought a kit for $20 and rebuilt the carb according to your instructions. This will make the rest of the winter in Anchorage a lot more bearable.
Great Video. Saved me a lot of frustration in repairing and keeping my 40 year Craftsman 7/26 snowblower running. Carb is repaired and running great again.
Your videos are much appreciated! I bought a 20 year old Simplicity snow blower last year. It ran great for a few storms. Then it ran rough and gas was gushing out of the carburetor bulb. I had no idea what was wrong. Looked up UA-cam for help and discovered your videos for rebuilding carbs. The brass float wasn't floating because of fuel leaking into it. I followed your videos for taking apart, replacing the float, adjusting the idle screws, governor arm, and throttle screw. It started on the first pull and is adjusted just right. I've never done anything like this before so congrat's for posting these videos!
Best video on the subject I have found. Helped me finally figure out how to put the little piece on the float. That little spring was a mystery to me until I saw your detail of this area.
Thanks for helping me get that engine running again.
Thank you, I have a MTD snow blower from the mid 1970s and the information and guidance you provided helped to keep it running. Thanks again!
Great video!! My snowblower had been whimpering for a while, and it is running strong now!! Thanks for sharing your wisdom.
I've watched several of your videos so far and they are great. Your work is very thorough and clean. Thank you.
Thanks dony, i adjusted the idle today as your video show us, my snowblower run as a new one!!! Perfect, thank you for your experience!
Thank you for sharing your knowledge!! I rebuilt my first carburetor and has brought new life to my Sears Power Brush! With sincere gratitude...THANK YOU!
Thank you - I have never commented on a video before - you do an excellent job doing these videos, explaining and showing what is going on. Your delivery of information is first-rate. Thanks again.
Great Video. I have now completed my small engine repair course. Your videos touch on so much more than the material we were given. Thank you, Jason from Manitoba
I like your clean and well organized workshop 👍
I'll admit. I have ALWAYS DREADED learning how to work on a carburetor thinking it was going to be super complex. Watching this has given me the confidence to go tackle the issue with the snowblower! Thanks for posting this!!!!!! If I would have tried to do something like this, I would get bleeped out the entire time while getting frustrated LOL
Awesome video. I rebuilt my 1998 simplicity carb, much newer but very similiar. Thanks for making seem so easy. I was very eager to dive into this project after seeing your video.
Thank you! Just replacing a carb actually but this helped me understand the function and install much better. Cheers!
thanks...it was the float..got the new plastic version. Now my engine starts up in one pull...thanks so much! You saved me a ton of money by teaching me how to do it myself! :)
BRAVO! Dony, you do very nice work. Thank you for sharing your knowledge. We all appreciate your wisdom and your ability to teach. We have learned so much just from watching your videos. It's also nice to know your videos are available for a refresher course ;)May God continue to bless you, your family and your business.
Gracias, Armando.
Nicely done! Very detailed and great job on the video images.
This was a good set of videos. Thanks Dony
Your videos are so helpful all I have to say is thanks :)
Awesome exactly the solution to what I needed. This was Perfect Dony!
Thanks!!!
Great video Dony.I recently purchased a used rototiller with the carb detached,got it home,installed the carb and would only run when gas was poured in the carb.I took it back off,ordered a kit,installed it,still the same thing,took it back off again this time I removed the welch plug and to my surprise their was a live small grub worm living under it along with dirt,strangest thing I ever saw! Cleaned it out,back together and runs like a champ now.True story.
lol
you're welcome and greetings from Ontario Canada
thanks, greetings from Canada
A1 job don. i sure like watching these videos.
lol, thanks for watching, there is also a link under the vid to purchase the carb kit
Great job dony!
All your videos are great and full of information don, I don't understand how anyone could dislike them lol
usually jealous and boring people dislike them
Great video, Don!! Real helpful.
Thanks for these videos donyboy73. These are some of the most professionally done DIY videos on UA-cam and I admire your motivation to help people like me (non-professional) make basic repairs to their own equipment. Blessings!
you're welcome
The mechanic returned my machine and sAid he was frustrated with it.
I followed your instructions cleaned emulsion tube and a blocked primer tube
My machine started first pull THANKS
raymond frank maybe you're the real mechanic
Awesome video Dony, thank you
very informative! 5 stars and on my favorites....thank you/merci!
Hello Don and all in the morning I will start my cleaning on my 6 hp torn snow throw built in 2000 I believe I will not remove for now I will remove bol and clean and float and needle and spray carb clean.
I will try this way first. Then put back and removed all gas with a baster add fresh gas a bit and remove again. Then add more fresh gas just enough to see if it starts. Plus new spark plug.
Don thank you for all you do for us.
Snow starts tonight.
Excellent video once again. Thanx
@donyboy73, thanks for this video. My snowblower only runs if I use almost full Choke. So I need to do a rebuild kit.
Nice an clean detailed carb job wtg! cheers
Thanks for the information. Saved me from buying a new blower. I have a 1970 Ariens that is made very well but I had to run it with the choke partially on. Now it runs fine thanks to your video.
you're welcome, make sure you are subscribed
Most professional self-help video series I've seen. If you're not teaching engine mechanics in school, you should be. Thanks for the help. Bob Z.
thanks bob
Another GREAT video Don.
thanks
Nice video...much better others I watched with similar instructions. I think I can go ahead and rebuild mine...Thank you!
thank you this video was very helpful
Hey Doc, You sure do a good job! AttaBoy!
Perfectly done.
great vid . keep them coming
VERRY NICE VIDEO !!!
THANKS !!
greetings from Germany
thanks for the video, very good information.
thanks dude.
very helpful and clear.
You talk about installing the needle seat with the ridge facing the bottom of the carb. To me, it looks like you installed it facing the top of the carb. You did have the carb upside down in the video. If the ridged end goes into the hole first, then it is truly facing the top of the carb. Is this correct?
Other than that point, it is refreshing to see someone present material like this in a professional and methodical approach. Keep up the good work.
Chris
Your videos are getting better and better Dony, great job!
thanks man
excellent video, wish I'd had it when I rebuilt mine
thank you!
very thorough. wouldn't have tried to do this job otherwise
Thanks for the great video!
I was always taught never to use gasoline to clean carbs because of its volitility and lower flash point in comparison to other cleaners you could use like kerosene, diesel or mineral spirits. But I guess if your careful enough not to clean them around open flames, sparks and keep the shop well ventilated you'll be fine.
Sounds nice for an old blower.
very helpful. thank you.
thank you sir
Excellent guide! Only advice I would add would be to almost completely unscrew the main needle valve in the bowl nut before screwing it onto the bowl. If the needle is too far in from the factory, you can ruin it when you torque the bowl nut.
Also the idle mixture screw needs to be installed with the bowl facing straight down otherwise the emulsion tube can be damaged.
great vid, thank you...
Had to replace the needle and seat on my snowblower. Thank you for the tips.
Didn't do a complete teardown... was just aiming to fix the gas leak and it wouldn't start. After the snowblower started right up to my surprise.
The old seat was completely clogged. Forced it out with compressed air which made the bowl float leak. $11 in parts for the two gaskets, clip, needle and seat...
+Clayton εжз that's good
donyboy73 Had to replace the worm gear too but that's another story. Nothing like a weather report to light a fire under your butt.
wow, thanks a lot
Another awesome vid! makes me wish I had a carb to rebuild... Wait, I do have that old lawnboy that needs some work...
that's good man, is there a video of them up?
thanks for watching!
nice job it start like it was brand new sweet
Here in Niagara Falls we all ready have 2ft. of snow on the grass.The most we got this year is 1ft.And I snow blowed with my snow thrower
Excellent videos - thank you. I got the kit and got my '74 Ariens running. I have gas leaking out and dripping from the bottom of the bowl though - thoughts?
When you adjusted the float, it looked like you had to push down on it to get it to touch the adjusting tool or drill bit.
Did I see that right?
question the white wire and the one coming off ign switch are they hooked together my engine is a h-60 they were unhooked when i got this machine
on these engines i often find that the exhaust valve leaks and causes similar problems
Great video, I have very poor eyesight when it comes to working on carbs, I would never be able to get that little spring in the hinge pin for the float.
I have very bad luck working on carbs, things don't run after I mess with carbs...LOL..
But I learned alot Donny, Thanks for your videos.
Thank you
Enjoy the vids donyboy73, thank you. I performed all the steps in Part I & 2, and rebuilt the entire carb with kit on a Tecumseh 7HP. Installed new plug, fuel line and primer hose, fresh gas, changed oil. Cleaned the carb thoroughly. Engine will not start. The electric starter and recoil works. Any other areas to look at? Thx for the help.
Donyboy73 great videos that's for posting them for us, I have a 1977 Ariens snowblower with the same card in this video but mine doesn't have a primer, now I went through and cleaned everything replacing the gaskets, float needle and the seat, also put new fuel lines, filter, and shut off valve and got it running but my problem is it'll only run on full choke I tried cleaning the carb three times thinking I missed something and I have the same issue, do you have any suggestions thank it'll be greatly appreciated,
Thanks Ryan R
Just rebuilt my tecumseh carb off a 7hl kohler engine which powers a late 1900s walk behind tractor!
Hey donyboy I have a 7/24 toro that I just did an engine swap on with the same model. Cant seem to get it ideling right. I watched your video on cleaning the carb and am gonna tfy some adjustments first. Any other tips you can vive me. The snow blower also in neutral inchs foward like its in gear. Any idesa.
great video, my question is that my carb leaks from the top of the bowl. New gasket, have taken it apart 3 times. Any suggestions
Cool video bro
thanks man
Here in the catskills NY we had a hard freeze last night . It has been up in the high 70s all week even hit 83 one day . This is weird weather ! If its global warming bring it on I love the warmer weather.
YOU'RE WELCOME
good one
Hello Dony. thanks for the instructions. I have a (I believe it's 5HP) MTD Snow King Model 317-550-000 with the Tecumseh engine. I was given this snowblower. It had sat for years. I cleaned the carburetor, but it still won't run good. Perhaps I didn't do a very good job...not like you did. I'm going to get the repair kit like you did. The main problem with my carburetor now is that it will only run on full choke making the control lever useless. When I try to "off choke" it dies. I believe I have everything out of adjustment now as I've been tweaking it to make it run on full choke. Any other pointers much appreciated. What I'll be doing at any rate is follow your video instructions. Thank you again.
J Nieto .
donyboy on the throttle linkage where can i get that long spring do they have a part number for it the only one i been finding is the throttle return spring on the shaft
thanks for watching
yes you can
Hey Dony, great vids. My carburetor is leaking gas from the tiny air intake hole...It just streams out and won't start. Is it an adjustment or need a rebuild? Or is the float not working? Also the governor arm is not attached to the throttle linkage but is connected to the carburetor the throttle has a bent wire thing that is all twisted up to be kept out of the way? I just got the machine its an old one but ran great last year. Its a 4hp 20 inch something like 900023 model.
Hello, I'm running into an issue where even though I adjusted a new float assembly like you did in the video fuel is still coming out of the carb from the top where the choke plate/throttle assembly are which leads me to believe it's overfilling. Is there potentially something I'm going wrong?
you're welcome
You should buy a Gunson colortune so you can see whats happening inside the engine after you clean and try to tune the engine.
Hi donyboy I have a Toro 521 snowblower , gas leaks out of the primer line connector and sprays out of the little hole above and to the left of it. Might I need to replace the Welch Plug and if so how do I do that?
Is there a way to bypass the safety shutoff on an Ariens 4 HP Model 922024 snow-blower with the attachment clutch engaged(auger/impeller) once the Interlock lever or Traction drive levers are released on the handles to keep the engine running? I'm fully aware of the risk but hate to disengage the attachment clutch every time just to keep the engine running. Thanks, great videos to watch!
Thanks for another great video! I'm working on my daughter inlaw's 20 yr old Toro7/24 with HSK70 engine. New carb is the way I would go for gas delivery issues but Tec has discontinued. I bought rebuild kit and proceeded as you so aptly teach on this video but cannot get more than 1600 rpm and lots of popping. I see that TEC has venturi listed as a separate part but noticed that you did (and other videos I viewed) did not remove it as you do in other videos. I also could not remove it as I have in large TEC engines. Are there any side holes in this ventury? By now I have watched tons of your videos and am pretty capable but having lots of trouble with this machine that was extremely well cared for and looks better than many 6-8yr old machines. I rebuilt carb on my aunt;s 36 yr old 7/24 Toro and that starts 1st pull consistently. Cleaned and adjusted ignition coil as well. It is an HSK70 130282U. Any ideas? I have viewed your vids on ignition issues and wonder if there is a definitive way to check the ignition module for spark present but maybe weak?
great instructional vid thanks
it may also be low on compression
donyboy73, thank you for all your videos... they're awesome and VERY VERY helpful. I followed your video step by step and cleaned out the carb, reassembled, etc etc. However, a few seconds after putting gas in the gas tank, fuel began to pour out of the carb/air filter. I checked the float, shaking it and listening for liquids and there was nothing. Do you know what is causing this? Thanks again for your great videos and look forward to reading your response. Have a nice day.
Another great video! Do you work on motorcycles too?Keep up the good videos.
yes behind in editing, you will see soon vids from a year ago
