Did this video help you?

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

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. 

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

goodfly1: love all the tips ,i have a 8hp snow king with a tecumseh that in dark you can see fire out exhaust and truns muffler red hot what could cause this ? thanks 

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

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

Craig Arndt: Very helpful Dony. 

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

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.

Brian Marzan: Hi Donyboy73, First, thank you for taking the time to film these videos. All the shops here in New England are backed-up for three weeks or more, with more snow on the way, so I’m trying to maintain my Toro snowblower with a Tecumseh HMSK80 the best I can. I just installed one of those $18 replacement carburetors from China. The blower is running better with the new adjustable carb, however it is leaking gas from the fuel adjustment screw. I’m having to use my fuel shut-off and then dump the bowl as a work around for the problem. Ideas on how I could fix the leak would be appreciate. Thank you.

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.

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. 

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!

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.

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!'

Kevin Logozzo: Hi, thanks for posting these, they are very helpful. I have ~2003 Tecumseh without the adjustable fuel mixture screw under the bowl. Is there a way to adjust the fuel/air mixture on this carb? I've noticed just this year a reduction in power where the engine struggles with even 5" of light snow. I have to go very slow. Now it's really starting to struggle and I noticed a blue flame coming from the exhaust when under load. Might have been doing this before but it's usually not too dark out and it wasn't noticed. Cleaned the bowl and jet although they looked very clean. I always use fuel with stabilizer. I am replacing the spark plug tonight too. Any advice?

Bertminator: I have a similar snowblower (as the older style), and wonder if you have an answer for me. Yy starter spins nice & smooth (no rough sound at all), however in -40° C weather, the starter gear won't engage the engine, but will still be spinning nicely. Basically the gear doesn't come out enough to engage the engine gear (flywheel or whatever you want to call it). I already lubricated the starter gear with silicone spray as well as penetrating oil (NOT WD-40), and still on cold days it won't engage. It engages fine if the snowblower is in my shop and warmed up. Any ideas or tips would be great. Thanks.

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. 

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.

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...

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

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.

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. :)

rojasj10: My Ariens 932 % + 2 Sno Thro with a Techmuse HS50 engine has had a problem from day one where it will only run with the chock closed even after the engine has been running for half an hour. As a result I have not used it much even though it is twenty years old. This evening I removed the bowl and main jet and everything looks new and clean. Just in case I cleaned the main jet. Of course the spark plug gets fouled up do to the way I have to leave the choke. Where would I start to fix this problem?

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.

d barboza: Thank`s for the help!

Pete Ciallella: I have an older Snapper 24" snowblower that has a 7 HP Tecumseh Snow King engine, with the mixture screw at the bottom. How to raise the running (high) idle? With the idle lever on high, the engine idle seems a little low. If I press up on the lever the idle will go up a little. Is there an adjustment to increase the high idle? I have a mechanical RPM gauge by B&S that I can use.

John Tumolo: Excellent job. Easy to follow. 

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. 

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!

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

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.

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! :)

tellebracht: Awesome! Runs like a champ now!

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

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?

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

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.

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!

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?

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 

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

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

INTERNA9: Thanx

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!

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

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

bilibob rut: My 8hp keeps backfiring like crazy on full throttle, what should I do? 

Big Rockk: Thanks a ton Dony, exactly what I needed to know. The old girl is running good now, as usual an excellent video!
