- Step by Step!
Today I'll be discussing carburetor adjustments, and showing you how to adjust a carburetor on a running engine.
While the adjustments are made, you'll see the effects in real-time.
However, before we adjust the carb, I'll 1st explain what these adjustments are doing, and how they're effecting the air/fuel mixture.

Some people watch their favorite Netflix show when they put the kids down for bed. Some people kick back, watch Eliminator Performance, open their ears and learn. They don't know what they're missing. Excellent content, as always!
Thanks for watching!
😊😊😊
@@EliminatorPerformanceive got a question for ya ive got a ms460 shes running pretty rick but the carb has metal limiters on the adjustment screws an I can't lean it out enough to get it to run good do you know of a way to get the limiters off?
Best information I've found about tuning my lawn mower carburettor. Thank you 👍🏻
This is the single best video I’ve ever seen on any motor vehicle. Only the best information given. No information on when he was born and who gave him the equipment blah blah blah… Lol kudos well done!
Thanks for watching!
Very glad I landed here since I just got a TroyBilt Chipper/LeafVac with a Tecumseh H50 engine for $25 and you're literally adjusting what looks to be the same carburetor that I just cleaned and rebuilt.
I literally was cleaning a carb for an 1980's H35 Tecumseh. Fiddled with the adjustment jet screw sort of on accident. Perfect video, now I know what to do, wasn't even looking for this and it popped up.
Thanks so much! My generator wouldn't start. Old/bad/ethanol. Took carb apart and cleaned and found main jet 100% clogged. Broke clogged w/a a sewing needle, then soaked all parts in a detergent followed by a gasoline bath and reassemble. Started first pull. But engine surged/hunted in idle. Removed pilot jet and used your wire brush technique and cleared the main passage and surging cleared up! Thanks to your video, my home had power in the next ice storm. Keep producing videos!
Once again, this was one of the best video on UA-cam on how to adjust carb, and especially show it in real
Thanks for watching!
For the first time I found a video that describes my parts and my situation perfectly. Too often there's enough difference to make me doubt what I'm seeing and have to adapt. Thank you so much!
I know this video is 2 years old but this is the best explained and most informative video on you tube for this topic... thank you!
Subbed and saved!!!
Dude this video is of extreme help. Ive been a mechanic for years and i have to say. Well spoken! And extremely useful
This is the best video I have seen that explains the adjustments needed on my old non-fixed carbureted SnowKing 5.5hp Tecumseh snowblower engine. Thanks for sharing the info!
Just bought a new carburetor and need to make adjustments to it. This video was very informative and educational. Great organization too! Thank you for walking us through everything and then providing the examples of the end points of the adjustment. Audio quality was great too for the examples! Much appreciated!
much, much appreciation. now have a starting point with my old carburetor. thank you for a GREAT explanation of how this works.
This is one of the best videos on explaining carb adjustments. I had the carb. with the adjustments. I fine tuned it and now works great. the last 2 years I started using TRUFUEL. Expensive yes but worth the outcome. Works great. Thanks
He explains and teaches very well. He is very articulate and is easy to follow and understand. Would definitely recommend watching to learn about carbs.
You are a God send. Thank you. My snow blower was running ruff, eventually died, and would not restart yesterday. Today I took your advice and turned out on the screw beneath the bowl that you talked about. That worked! It started up and ran. Now my driveway is clear of snow. Glad I found your video.
Best description and explanation of these carbs I have yet seen on UA-cam or anywhere. Thanks.
Thanks for the explanation on carburator adjustments. I had rebuilt my snowblower carburator but then it would only run with choke on. Watching this helped me in finding and setting the air mixture screw.
Awesome video. Great info. All we have in my area is ethanol fuel so I do my carbs annually to be safe. I am doing an old 1987 Toro snowblower that I've had since new and has been sitting since 2013 when I bought my next Toro snowblower and this has explained everything and then some perfectly. Thank you.
Great Video. Helped me sort out my issues with the carb on my snowblower and its running better than it ever has. You explained and then demonstrated very well. Cheers.
Your presentations are organized, clear concise and … well, perfect. You speak clearly, and with authority. You use proper grammar and at a perfect cadence. Those are qualities some people take classes for and most never achieve. From the beginning of the video you state what you are going to cover and start right in. And you actually cover it. On a one to 10 scale, I’d give you a flat 15. You are really good.
Thanks for the kind words!
Great filming! Very clear explanation. Watched this video, walked out to my garage, warmed up the snow blower, made these adjustments. Running as good as new! So important to understand the high and low RPM adjustments - especially on my non-adjustable carb! And how small is that hole in the end of that fixed air/fuel screw - wow.
Thanks for watching, glad it helped!
I almost always forget the thumbs up when I see a good video. Thanks for taking the time to provide knowledge to us.
Again, your a great teacher. I’ve watched this video numerous times to reinforce what your explaining. THANK YOU. I’ve been subscribed for a little while now. I started my own small business from my home repairing small engines a year and a half ago, (I’m retired from my career), you have been very helpful to me. My hobby that I love has now transformed into a positive cash flow that I really enjoy. Again, many thanks. Be safe friend.
Thanks for the kind words, and thanks for being a loyal viewer! Small engine repair is actually incredibly simple, once you understand the basic fundamentals of how engines and equipment works. Once you have that, you start to realize, every unit operates in the same way, they're just assembled in different ways, with different parts. Good luck on your business!
Done your self proud son.good explaning.i learned something.im 64yrs old been working on small engines all my life.i hate those carbs you cant adjust with out having to scrap the blower down.im working on one now a brigs and stratton only been used about 10 uses.now i have to scrap it down and fix it.i worked on just about every small engine there is from out boards to hit and miss engines.chainsaws to leaf blowers but i hate those carbs the most.gm.😂
My Dood! Thanks so much for making this video! I replaced the carb on the old rototiller I bought. Followed your directions. It is now PURRING...super smooth. Looking forward to planting a garden this spring now. SUBSCRIBED. :)
Starting on a Tekumseh that is surging really bad tomorrow morning. On a Snapper snow blower. This is just what I needed. Thanks!
You are the cake boss of carburetors. Thank you sir, for your service.
I'm glad I found this vid. You've explained it cleanly and in simple terms. I'm now subscribed for future tutorials.
So far the best video tutorial on how to adjust snowblower carburetor I have seen. Great job 👍
Thanks for watching!
First time I watched your video and I'M IMPRESSED! Accurate, precise, and very informative. You learn a great deal in such a short amount of time. Thanks for your time. Well edited, well spoken. A+++++++
Thanks for watching!
I've watched a lot of how-to videos and search through these things for the last couple of years I'm glad I found your channel Thanks for being so informative and keeping it simple at the same time it helps out a lot I appreciate it thank you you're doing a wonderful job man keep it up
Thanks Michael!
Great video Brother... I can remember way back when, picking horizontal shaft lawnmower engines to mount on bikes to make mini bikes (and trying to outrun the cops)... The starting point of those engines was 1 1/2 turns. Nice to know some things never change.
I don't normally comment on videos but I just have to tell you great this video is. Thank you!!!
Very nice explanation tech. It's clear you are above average in your field
My lawn mower was ;surging / hunting so I went on line for that symptom,for that type of mower and they said to be sure the vent holes, in the gas cap weren't clogged.
I blew air in the holes in the gas cap, and it WORKED! The engine leveled right out to a steady speed, problem solved!
The gas tank was drawing a vacuum because the vent hole were plugged and engine was starving for fuel. Easy fix and worth a try!
You just helped me out immensely. I forgot/ didn't realize I needed to clean the pilot jet on the carb. I always do it on the Hondas and Kohlers but just dropped the ball on this one. Probably forgot since they look different. Thank you so much.
Thanks for watching!
Awesome video! Thank you for clearing up all the questions about adjusting a carb!
Very good video, love watching videos that teach. These machines small engines are so simple and easy to work on compared to cars. You can fix anything with basic tools
very good and thorough info. i've been a shade tree diyer for years, this is really gonna help, thnx from massachusetts.
Great breakdown on carb function. I have a Walbro LMK with the adjustable main jet and could not figure how to start adjusting it. Thanks!
Thanks for doing this video. I have a very old Ariens Snow Thro with a Tecumseh 7hp that was given to me because it didn't work. After replacing the Pinion gear I tried to start it, and it didn't run either, Ha. Rebuilding the carb was easy BUT I didn't know how to adjust it once it was running. Now I do, thanks to you.
Superb videography! Clear, concise explanations! Direct, and to the point!
I watch a lot of different channels I think you're the best teacher on UA-cam on small engine repair
Thanks for watching!
Wow! That was a lot of amazing information. I've had some small engine training back in the day, but you really do a great job of going into great detail. Thank you very much.
And the gas tank that's also sufficient right and put fresh fuel in it next season
Wow what an excellent video, this is a great video for carburetors for dummies, well done. Thanks for sharing
Life saver man! Best video I’ve seen on this topic. Thank you!
Thank you so much. The video was very informative you made it very easy to follow I learned in 20 minutes what would take weeks of theory in school. Great job!
Cleaned out the hole in the screw, worked like a charm Thanks
Great tutorial! I've got an ancient hand-me-down Simplicity 860E with a mystery horsepower Techumseh. I just replaced the carb today and both fuel/air screws were all the way in and bottomed out. No big deal armed with your tutorial though!
I've been in mechanical services of one type or another my entire life (I'm 64 1/2...when did THAT happen?!) but adjusting both screws is definitely an art. I found a balance I can live with tho. I was having an issue with not having the main jet adjusted to the sweet spot and went I went from idle to full throttle it just went bauuuuugghhhh until I moved the throttle lever back down toward idle. Watched the adjustment part of your video again, started from square one, and I'm happy with the results. There's an occasional pop from the exhaust at all speed ranges (spark plug got replaced too btw) but not horrible.
It's 75 degrees out today here in SE Wisconsin so the true test will be when our winter temps slam down below zero.
I need a carburetor like the one shown in the video on the right side with an adjustable idle air main jet screw and an adjustable low idle screw. Also the carburetor bowl has an adjustable screw on the bottom. The carburetor is from a Tecumseh HMSK80 155443S model. Great video!!!
This is one of the best videos I have seen explaining carb adjustments. You are right about the ethanal in the gas breaking down, but few people if any will search and find ethanal free gas. This is why I tell people to always drain the gas and let all gas run out of their equipment . I have been a small engine repair tech for 40 years and you would not believe some of the gummed up carbs I have seen. Keep up the good work !
Yea they get pretty gummed up, thanks for watching!
One of two brothers that owned a large boat shop told me a few years ago that adding alcohol to gasoline was the best thing that ever happened to their repair business.
Great video and greetings from Ontario too! Just getting acquainted with an older Tecumseh 10.5 Hp. Thanks for the explanation.
Wow I can't thank you enough. My skid steer was down and I have a 600' driveway. to plow My 8 HP 36 year old Toro wouldn't stay running. Your video explained the problem perfectly !!!
Thanks for watching, glad you're back up and running!
Great explanation my fellow Canuck! Well done.
I am resurrecting an old snowblower that has sat for many many many years in storage to have ready for my daughter next winter. I drained old fuel and used premium fuel, cleaned the carb passages and still have hunting issues. Note that the governor pivot point was stiff from rust but have freed it up so that it moves again.
I have the carb style you showed that has an adjustable main and an air screw.
When the engine was warm and at high throttle, I opened the main to try and get rid of the hunting but would not go away and eventually it started to flood. At this point the main was open a large amount at 3-4 turns and took a 1-2 turns back closed to clear up.
I’m thinking I still have an issue with the carb internals or the governor.
Excellent Video, Great job Explaining these carburetor Functions.
Over here in Australia, have just commissioned an old tecumseh powered lawnmower with a very similar adjustable carb as you show here. I had it close to running spot on but ur information has been a great help so Thankyou. You Americans are always very helpful and are happy to share knowledge for others! Great job!
I'm Canadian, and thanks for watching!
Oops I’m so sorry! Like calling a kiwi an aussie!! They don’t like it either! Anyway, apologies for that! I’ll work some more on my accent recognition!
Great job!
I have an Ariens PathPro that surged like mad. I pulled the idle jet and used a vise drill, but probably too larger than what I should have done. The surging stopped, but now the engine pops, like a back firing of a car. Any suggestions? This is an LCT engine, can I get a new idle jet for it? If so, please send a link where I can purchase one. Thank you.
99204-ZE0-0350 and drill to desired size
@@EliminatorPerformance thank you, but I don’t know what these numbers are for. Please explain since it may be what I need. Thanks
Excellent job explaining. Now I'm ready to fix mine soon. Subscribed and ready to learn more.
One thing I found out about adjusting the carb on my snowblower is do not adjust it when it is warm outside. I adjusted mine when it was 70 degrees outside. When I went to use it for the first snowfall, it was running very lean and had to richen it up a lot because it was colder outside. Meaning the air was denser and needed more fuel. lesson learned.
Thank you very much for that tip I think that's my problem with my snowblower the adjustment on the underneath the carburetor
Fantastic video. A wealth of information here, clearly explained.
One of the best video explaining carburetor adjustment thank you so much I learned a lot
What an awesome video! I subscribed! I have an 8HP Tecumseh HM80 with a Walbro LME49. This video showed me exactly what I needed to know. Thanks for the excellent info!
It's really an informative video explaining why and how to adjust the carburetor.
Great video as always, inspired me to go and sort my lawn equipment carbs out!
You can do it!
Best video on the net on this content!!!!!!!!!!!!!!!!!!!!
I just picked up the same machine I like that tip on if it was sitting for a while just unscrew that bottom screw run till gas build up thins out. Didn't see the video so I took it apart . But your video is very well done thank you blessings
Great Video! Thanks so much for such a clear and thorough explanation!
Outstanding description.
I just sold a craftsman blower than started on the first pull for 13 years every time. Changed the oil every other year and gave it more premium gas when needed. Never any stabil or anything. That brings engine was amazing, but the machine seemed to be struggling to move the heavier snow.
Just bought an ariens 10hp ax engine blower - looks great, but it took about 10 pulls to start at pickup. The guy said it had never been started, which I thought was weird since they had put fuel in it.
So my question is; what can be done about cold starting?
Couldn't run my snow blower on anything other than ether. Cleaned that idle jet and it started right up. Thank you !
Great in depth explanation as always. Keep up the good work
Thanks for watching!
thank you for this. exactly what I needed. you have a great way of explaining things
Sometimes a guy just needs a refresher on the basics, great video!
Thanks for watching!
Nice explanation, I try to always get my customers to drain the carb. and fuel tank if possible. Thanks for the video.
Thanks for watching!
The best video I've seen on this. Thanks much.
Fantastic video. Thanks for all the detailed info.
Thank you so much for the explanation, as well as demonstration!
Very informative video...Thank you Young Man...
Excellent as always. Thanks
Wow another great job EP. Thanks for all the well explained videos you provide and share.
Thanks for watching!
Great informative video! Excellent production value.
Excellent. Very good easy to understand and grasp explanations.
Good job. One of the better carb diagnostic/adjustment vids on YT. Few things to add...
1) nice job explaining carb schematics and what jets/adj. do what. One thing to add before the drill bits come out, make sure intakes don’t have any air leaks and air filters (if equipped) are in place and clean...snowblowers not so much of a concern.
2) fuel preservation only happens if stored in a sealed plastic gas can or tank. It will not stay preserved in the carb bowls.Tyrall has finally come around to my understanding and knowledge with his fuel stabilizer test.
Subscribing and will be catching up in your other vids. Keep up the good work! There ain’t many of us left that know this stuff anymore!!
Thanks for watching!
I might add that welding supply stores sell cutting torch tip cleaners that are excellent and cheap. I used to use them when I was working on commercial and residential gas equipment
Excellent video..!
Thank you sir.
Great video! Very helpful thanks!
good vid.....having trouble with my older blower.....gonna try suggestions....hopefully I can get it going before the snow....peace.
awesome video, i too watch your several times, thank you
Absolutely great video. Your awesome
EXCELLENT VIDEO ! .... "Nuff Said !"
Wow, just stumbled on this as it was in my home page. As mentioned below , this was an excellent step by step with a concrete why? attatched. Have an older snow king and I've watched several videos. Also wondering which carb and why to maybe just replace the old one as opposed to rebuilding. Now a subscriber! Thanks!
Thanks Thomas!
@@EliminatorPerformance Thank You!
I have a non adjustable carb and the kit I bought included the washer and o-ring for the adjustable idle mixture screw. After refurbishing the carb, the engine was hunting so I converted the fixed screw into an adjustable one by finding a suitable spring and using the other parts. So even with the predrilled screw, I was able to adjust the mixture and smooth out the engine and get a good idle.
To clarify, you removed the fixed regulator screw on the bottom of your brand new carb and replaced it with your old nut, screw and spring from your old unit? This made your non-adjustable unit adjustable? Is t that easy?
Great explanation. Thanks!
Thank you Brother good explanation and good video have great day.
Great information. I have several to get running .
Great informational video
Excellent explanation! Thank you.
Absolutely Outstanding
Love going to school with a good teacher thanks for the lessons
Thanks for watching!
Great info. Thanks for the education!
