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.
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.
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.
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...
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.
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.
Frank Rivera: Donyboy,
Great video! Thank you for all of that useful information.It wad just what
I needed to learn. Thanks again!!!!
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.
bilibob rut: My 8hp keeps backfiring like crazy on full throttle, what should I do?
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.
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.
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
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.
thersten: Great job. Once again your videos are the best videos online!
Clare Dejong: I like that you kept it simply.
Thanks for the information.
brysonz: Great video explanation! My craftsmen 9 HP is surging and the muffler has
flames inside. This should so the trick.
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
Craig Arndt: Very helpful Dony.
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
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?
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!'
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.
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.
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?
Ian Gans: Thanks, dude. Super helpful. I have an old Ariens, but the carb is
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
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.
d barboza: Thank`s for the help!
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?
george flanagan: Thanks donyboy73 folloe your 3videos on 8 hp carburetor and works fine on
my snowking snow blower thanks again
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

replacing padles and scraper. Any ideas. Thanks tim
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!
tellebracht: Awesome! Runs like a champ now!
angus kangus: As a new home owner I have to say your video's have helped me a lot Thank
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?
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
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
