Did this video help you?

Joe W: I've got an older Tecumseh 5hp snowblower. I bought a brand new carb off Ebay (Tecumseh branded). It runs great for 2 minutes and as it gets warmer runs poorer and poorer as it gets hot. I'm stumped. Any ideas? Points? Coil? Spark seems fine. 

aaron schoessow: Hello I have watched your video on how to adjust the carburetor on my Toro it is a 8 horse. Tecumseh engine. Still seems to backfire out of the exhaust quite a bit... I pulled the air mixture needle. Also have turned out the needle at the bottom of the float bowl. Turned it all the way in. Then out one and one quarter turns. I also did this with the air mixture needle so it is at one and one quarter turns out. The cover on this, I have removed, for easier access... Will that cover make that much difference??? Also I just bought a new fuel cap. Any suggestions you may have or questions please feel free to ask. Thanks for the help...

Frank Rivera: Donyboy, Great video! Thank you for all of that useful information.It wad just what I needed to learn. Thanks again!!!!

Robert Jackson: First, thanks for taking your time to make these good videos. I have an Ariens snow blower w/ Tecumseh engine from 1992. For the first time ever, I have to run with the engine fully choked in order to use the snow blower. I am no longer able to back off the choke and keep the engine running as in all previous years of use. Do you think I have debris in the carburetor or do i just need to adjust the main jet by turning the adjustment screw as indicated in your video? Should I remove the bowl and clean it out first? The bowl has never been removed. Thanks, Robert

The89stang1: Donyboy I have a early 70s Ariens snow thro snowblower, when i run blower i have to keep it one setting away from full choke to keep running properly. I have the second style carb in this video which i never took apart before. When i take out screw on bottom of bowl does it have jet attached, i have cleaned that style jet before just wondering if old style has jet. This is my guess for needing choke jet needs cleaning. Any help appeciated.

bmbell1919: Hi Donyboy. I have a 1994 Toro 38180 snow thrower. By design, there is no low/high speed setting. I am confident that the carburetor is clean, the spark plug is new, and the oil/gas is fresh. It starts after a pull or two, and sits idle at about 4,000 RPM. However, when I engage the augers, that drops to about 3,500 RPM. The issue that I have is that the machine is unable to handle anything greater than a few inches of snow before near-stalling. There are three screws that can be adjusted on the carb itself, and then the governor arm. Forgive my amateur take, but I know one screw adjusts the idle speed, the second may be the fuel/air mixture, and I don't know what the third does. I need help understanding where to start making tweaks to the carb and governor arm. My method (trial-and-error) is frustrating at times. I am sure there must be an order to the steps, and if they are done out of order, you end up in circles like I am now. If you or anyone are able to assist I would be most appreciated. In the right hands, I know this machine would be amazing.

Garry Burgess: I'm buying a brand new Honda snowblower, but I want to watch as many videos like this to make fewer mistakes than I made with m MTD, which still runs OK, but I'm giving that to one of my kids. Probably what saved me all of these years was fuel stabilizer.

sammy 9000: Hi donyboy. I have Stiga snowblower with 8hp Tecumseh and i have a red glowing exhaust mufler when running full gas. Engine works fairly good maby litle misfire and some blue flame comes out to mufler, you can see flame and red glow clearly when you run it evening when its dark outside. Reason why i ask should i do something to fix it cause i dont want to burn exhaust valve or something else. What you think is this problem fuel mixture issue engine running lean or is exhaust valve clearence too small and valve doesnt close full? Carburetor is that newer model, nozzles cant be adjusted. I measured engine compression cold motor and it showed 55psi is that good or bad to that engine? Maby i should measure it again when engine is hot... cause if valve clearance is too small valve won't close fully when engine is hot i think? If this problem turns out to be too small valve clearance, is the job to fix it pain in the butt and do you have a video where you do a similar job. If i find there allready burned exhaust valve can i find somewhere a new valve to this motor? I live in Finnland and i'm pretty sure that i need to order it from USA cause this blower is probably around year 2000 model and the spareparts this old model is hard to find our retailers. Sorry my bad english and thanks if you bother to answer. :)

TheGurtsmen: Thanks a bunch. My dads snowblower ran like crap for years. Cleaned the carb and tweaked the screws as you did... Good as new. Great video. 

Darryl Voight: Thanks a lot Donyboy! I just got an old used Snapper 10HP, 30" the other day before the "big" storm hit NJ. It ran very rough and only with the choke on at first. But after watching your video, I was able to get the idle and full power operation to work just great. 

Katherine Niebla: Donyboy you speak clearly and slow enough for me to understand how to fix my snowblower while working on it as well. As a female just learning how to fix things myself, I want to thank you for a great training you gave me on the belt tension as well as carburetor.

Clare Dejong: I like that you kept it simply. Thanks for the information.

Jim Bigger: Don, I recently put a carb kit in My Tecumseh 10hp and adjusted it to your recommendations. I found it wouldn't stay running but I moved the engine speed governor Linkage and it stayed running and ran perfect. I havent used it since until today and it will not stay running. It's like once the fuel from priming is used it dies. I played with the linkage a little bit and it would stay running but at a very low rev. As soon as it tried to rev up - it would bog out and die. Any suggestions?

bobriguez1: Thank you, thank you, thank you!!!! My Tecumseh Snow King decided to run like crap today(during a blizzard)... these adjustments made all the difference!

Theo Macris: Bummer, just used your settings on my toro 824. The engine idled up too fast and promptly blew the engine, I assume a rod since there is no compression. So much for that.

brysonz: Great video explanation! My craftsmen 9 HP is surging and the muffler has flames inside. This should so the trick.

78726222: Donyboy...I have an MTD with the carb with a fixed jet. When snow would dump onto the carb side if I his a drift it would run rough then be ok. I imagine from aspirating snow into the intake. This time it stalled and now wont start even using electric start. I drained some of the bowl with the drain valve but not all of it thinking if there was water it would drain out.

thersten: Great job. Once again your videos are the best videos online!

Bob Berg: Hey Dony I have a 1980 model Toro 7/24 and after a motor swap with same year and model the blower does not run. I may have hooked up the linkage wrong or set the carburator up wrong. It ran for a littl;e bit and then I was not able to start it. I did a minor rebuild to the carb and still no luck. 

Carl Zorro: what can it be when you go toward the snow but it turns off as it's going to intake the snow to blow it out?

d barboza: Thank`s for the help!

Ian Gans: Thanks, dude. Super helpful. I have an old Ariens, but the carb is identical. 

Craig Arndt: Very helpful Dony. 

Cheryl Everett: My husband bought an old tecumseh snow blower last year. It wasn't running that well this year. After watching your carb cleaning and adjusting videos - it now runs fine. He says 'thanks for the great videos!'

Garry Burgess: I was pretty unhappy with my MTD that had a lot of problems that it should not have had, even when brand new.

Susan A. Enns: Thank you very much for an easy to follow video. You made it simple for someone who knows nothing about carburetors. Much appreciated!

guitartec: Should the choke be off to do these adjustments?

Verne Potvin: Have a Tecumseh 10hp with fuel dump at bottom of bowl and adjusting screw. Question....I have set up the governor etc and adjusted the fuel mix and idle. But as oon as I put it under load, the unit bogs down and quits. Any suggestions ????

97197mech: Donyboy, I'm trying to fix my neighbor's Toro snowblower with Tecumseh HSK60-76008B (H) DOM 6853D Engine. The problem was it wouldn't run without the chock on fully and even then it cut out every minute or so. I removed the carb and found the float was not adjusted properly and the needle valve seemed to be sticking. I soaked the carb overnight in carb cleaner then put a wire through all visible passages, installed a carb kit, adjusted the float, set the idle mixture screw to 1¼, set the bottom mixture screw to 1½, drained the fuel and refueled with fresh fuel. Now with everything reinstalled I can only get it to run for a few seconds with the choke full on. I've attempted to adjust the bottom mixture screw out but still can't get it to run more than a few seconds. I'm thinking there are other carb passages that may need to be cleaned behind the blanking plugs. Should I remove them and clean the passages? What is the best way to remove/install them? Thanks for your help. Did I do a thorough enough cleaning?

Raman B. Chauhan: Million Thanks. I followed your precise instructions and my 27 year old Sears Snowblower is still chugging along without ever visiting a shop. Thanks so much for posting your videos. You are doing us a big favour. Seasons Greetings to you and your family. 

Wayne Perkins: Thanks donyboy73, Without your video I'd have been lost. Followed your suggestions and darn if the John Deere 828d snow blower seems to be running and idling the best it has in a long while. Thanks so much for posting your videos.

george flanagan: Thanks donyboy73 folloe your 3videos on 8 hp carburetor and works fine on my snowking snow blower thanks again 

Bruce Albarado: hi donyboy73..I have a 8 hp techumseh snow blower I just replaced the throttle control arm.Put my linkages back where they were.If I throttle up it wont throttle down..not sure what is happening any ideas would be helpful..not a small eng guy but have learned a lot from watching your vids.need help here I'm lost on what to do...please help

Jim: So my blower would not stay going when i closed the choke - only stayed going with choke on. I adjusted the engine speed governor and it stayed going when I closed the choke. Was that the best adjustment/ solution for my problem? Thanks!

pei bossman: very good, thank you...

aWoodchuckTunaMelt: I recently acquired a snowblower with a Tecumseh HMSK80 engine from my grandfather, and long story short i dont have nor can get the original carb. According to the owners manual it had the non adjustable carb on it, I, not realizing it at the time, purchased an adjustable model. After installation and despite my best efforts to tune it it just wants to surge. Are the jets on the non adjustable model carbs bigger/smaller? Iv spent hours fiddling with the mixture screws to relatively no change. Any help would be greatly appreciated, im at my wits end with this thing!

Jim Bigger: It has the fuel mixture idle screw and the float adjustmen screw on the bowl

Vin Bellissimo: you and I must have learned the same hard way... I drilled out the cover on my old Simplicity so i could get to the high speed screw. I find your videos very helpful 

Tim Miller: Hello don I have a 17" snapper le and it doesn't throw snow well even after replacing padles and scraper. Any ideas. Thanks tim

tellebracht: Awesome! Runs like a champ now!

INTERNA9: Thanx

78726222: thanks I will try wiping it. I pulled the plug wire but didn't see it was wet. Where is the intake to spay into?

angus kangus: As a new home owner I have to say your video's have helped me a lot Thank You !

ugotit33x: Excellent explanation thank you

Stokersrule: I bought my snowblower used a while back and was about to replace it after trying everything, including a trip to a small engine shop, to get it running properly. After this tutorial coupled with your governor vid, it threw like a new machine last year. I just realized I hadn't commented while telling a family member about it. Anyway, thanks so much, great job! :)

RUSSELL PETERSEN: I REBUILT MY TECUMSEH CARB OLDER MODEL 825. IT IDLES GREAT BUT WHEN I TRY TO INCREASE SPEED IT DIES EVERY TIME. PLEASE HELP

78726222: got it. just needed to remove the cover...

Richard Kim: Great Video, Donny. I followed your 3 step process to rebuild the Tecumseh carburetor on my Toro 521 snowblower. This video completed the repair to get it running at top performance. Thanks for making it VERY easy to follow.

gerry6310: As usual Donny, you make a great video so I can fix this items myself, saves me a a lot of cash On a pension now

sparc500: Thanks a lot.. very clear explanation, I got a new carburetor for my Tecumseh and needed an explanation of the process to go through.. works great now.
