Did this video help you?

patrick cordery: how old is that snow blower it sounds like it runs grate since u fixed it

tony Kari: Hey Donboy, do you have a video on how to clean a 15hp Tecumseh riding lawn mower Carb. My dads mower only starts on starting fluid for few seconds than dies out. I'm thinking the main jet is gummed up from old gas. Thanks 

Mike Carrington: what is the best way to avoid gumming up a carb - I have an old atlat I bout at a moving sale - works good - should I run it until its out of gas at the end of winter? I used stabilizer this winter with gas in it

Caleb Tutleman: Already have the carburetor apart and now I need to buy carburetor cleaner, wish me luck, and oh I'm subscribing because you are a very intelligent person

spawnofdawnacle: Thanks for this video. I wouldn't have gotten my tiller running without it. Very nice presentation.

BolensG8MowerMan: Great video mate! It's amazing how a machine as old as that, with a bit of work runs so smoothly. Great job!

Paul George: This is a great video. I have an 8hp simplicity snowblower with a briggs and stratton, very similar and i was able to follow this step by step. Thanks a lot for the video.

G. Reyner: Liked your video. Does the float needle have a tiny o-ring in its seat?

Geoffery Carter: You've helped me a lot thank you. Its always good to have a good teacher in the house=]

T. Charles White: Great Video Dony! Your instructions are clear, detailed & easy to folllow, Thank You! I have subscribed and I'm adding your video to my Small Engine Repair Playlist. Keep up the great work! P.S. Echo & Briggs & Stratton should sponsor you!

Pocketraisins: Hey Dony. Great vids. I do have a question though on the two piece Briggs carb. Is there a "good" procedure to drilling out and removing the emulsion tube? I have a kit coming and the old emulsion tube was so tight even after soaking in lube a few days I buggered up the screwdriver slot on the end. I will have to drill it out to remove it. Thanks.

1secondarysystem: i have the same engine just its on a toro but when i revve it like you did i get black smoke like you did do i just keep turning it in until it stops doing that 

Bob Romanko: Don, I just worked on the exact same carburetor. Instead of running like a new engine, mine leaked fuel as if I owned stock in BP. I've determined the body is warped, so I'm going to take the carburetor back off, disassemble it, and surface it on a granite block with emery paper. Your shop must have good vibes, 'cause it sure seems to have better luck with ancient engines than my shop does. BTW, my main needle jet has become one with the carburetor body, and I've had it soaking in penetrating oil for three days, but it's decided it doesn't want to part company. That makes working on it a lot more interesting!

boosted22g: could you post a close up of that governor setup? i have that exact setup and i'm having a hard time with it... former owner took it apart

Caleb Tutleman: No it's not giving off a spark, I feel current and tested it, it's 5.0 volts, and sorry for the wait, my gmail was not working correctly.

Dan Martin: Awesome video donyboy! Very easy to understand and follow! You have solved my B&S 8 HP Powermate 4000 generator problem! Keep up the great tutorials--they are very much appreciated!

Curt Lefevre: Great tutorial, followed the steps on my old Toro 726 snowblower. Started right up but stalls when warmed up and choke off. Runs a while at 1/2 choke but stalls after a minute or two. Any suggestions? 

1secondarysystem: iv got a 1972 8hp briggs and i keep forgetting how much oil to put in it every year i think it takes 44oz but im not shirr do you know how much it takes?

T. Charles White: I have a Model: 109720 Briggs and Stratton engine. It is on a Garden Way/Troy Bilt 24" Tuff Cutt. The engine runs good but it leaks gas right beneth the screw that holds the air cleaner in place. What are the possible causes for a leak like this one.

TONY A: Thanks for the video. Really helped. Do you know the float settings? My chipper runs for a short time then quits.

Damon O'niel: Hi donyboy73 I have a 8hp Briggs and Stratton engine and I have rebuilt the carburetor multiple times but the engine will not idle. Even when I adjust the fuel jet. Any ideas why this is so?

718mattmatt: I have an 8 hp brigs on my log splitter and I'm having trouble with the carb 

roboink: I have a Ford snow thrower with the same engine and I want to rebuild the carburetor. I have the kit..I have never rebuilt a carburetor before, but am mechanically inclined...same steps as above to rebuild..? How about adjustments..? The kit is asking about a float needle valve if its Viton tipped or aluminum. I don't have the carb off yet, so not sure what type. 

ezover: any ideal how to find a part number on these? i have a older generator with this carb and i would like to buy a new.

Stevet19791: Great video!!! I have an 8 HP Briggs with an up draft carb that I can't get it to quit leaking out the bottom, watched your video and others 100 times and put new carb kit in it 3 times any suggestions would be appreciated??!!

Mark S: Great video! I've got that exact same engine and carb, but the model number has been rubbed off. I need to get parts for the carb, but they need a model number. Can you please tell me the model number listed on that engine? Thanks!

SykesATL: I am helping my neighbor rebuild this same carb the instructions are great. His carb is leaking fuel through the screw in the bottom that also serves as a mount. In the video, you just simply removed this screw. Is there supposed to be a washer or gasket?

Desmond Brady: thanks was helpfull we had a lot of snow and snow blower is working great thanks again

Eric Romanowski: Great video! This is my exact snowblower. If I accidently took out that bottom float screw (not with the bolt). Is there a good starting point for the screw? I have good spark, fuel looks good, but it just fire up. Fuel is spitting out the air intake too. =\

donyboy73: @theoldwizard998 the tank was clean and i also replaced the fuel line

Carl Bryson: Donyboy73, I have got a question, On my Electronic 8 Hp briggs Vertical Shaft, there is a wire leading from the Coil going to a bracket on the side of the engine, when that wire is connected to the coil, it doesn't have any spark, when i Disconect the wire, I have got spark, What is the Purpose of the Wire? Let me know what you think, Thanks

donyboy73: merci Guyaume

Jonathan Newton: Very, very, very good. Top quality, extremely well taught. I'll just have to check your other clips out! Thanks!

The Small engine guru 1: Hi Don, I have a John Deere GX 75 riding mower which I had running yesterday, after it had been sitting for 2 years. It has a Kawasaki 9 hp fc 290v engine and is getting fuel and fire, but it back fires at the Mikuni carb. I have cleaned the carb and the jets on it, but now it won't start. Do you have any suggestions as to what I should try next? I'm trying to learn everything I can about small engine repair and would really appreciate any help! Thank you for your time and advice.

Doogmatik: j'ai une souffleuse toro 8hp briggs meme moteur que ta video. je voulais savoir quand je baisse la commande de gaz au minimun, si c'est normal que le moteur arrete. merci

warriordriver350: It diddnt seem bad at all, its actually called an updraft carburetor. Im just curious what year?

donyboy73: good job!

ZippoVarga: As with all your videos Dony, you do a thorough and comprehensive job of explaining the ins and outs of the items you're working on. There was one step that I noticed was missing though. Leveling the float using a flat surface and placing the top carb body on the flat surface and adjusting the float so that it's perpendicular to the level surface. I've failed to do this in the past and had a float that wouldn't shut the fuel supply off before the fuel spilled out of the gasket. Just a thought!

donyboy73: check float setting and you may need a new seat and needle valve

ray klein: Donny, I have a Troy 8hp rider, runs but when I shift or engage blade, it stalls out, will start right up again, but always does same. It ran well until brake failed and I hit a small curb, resulting in a blown fuse which I replaced. Any ideas? I still have to adjust or replace brake too. Thanks

Farmalls Farms: do you make good money like this?

John Duque: Thanks for the vid donyboy, I just want to ask how many turns out should I set my air needle if I took out aswell during the cleaning process?

Jerry Conley: Glad I saw your video. I have a Briggs 8 HP on my generator and have not been able to find the engine model listed anywhere and need to clean my carb. I know I need a gasket, but can't find one by my engine model number. It is 134417 Type 0123-01 Code 91M0110. The carb does not have a part number on it. So, I'm hoping you can tell me whet the part number is on the carb you are cleaning in the video because it look identicle to mine.

donyboy73: @patryric thanks for watching

CHIRODEA93: Hey. I have a tiller(Ferrari 90, LOMBARDINI IM 350 engine). I cleaned up the carburetor and when I accelerate him, his acceleration going down just like something are choke him. And when I dig with the tiller the engine die. I give you a sugestion from me: by the carburetor is leaking gasoline. May be this the problem?Please help me

chet3larson: Sure you have heard this a hundred times by now - that is actually a Gilson, branded for law boy and is one sweet machine.

Craig Arndt: Cool video. That's an old motor, but runs sweet.

MrDavidNickel: Thank you so much for shwoing this, I know I asked about this last fall and appreciate all the videos you do. I learn ALOT from your "how tos". Please, please keep up the good work!

siemenstraffic: That Lawn Boy snowblower looks like it was manufactured by Gilson

UnsworthDeadmond: I can't thank you enough. I will see what I can do with my 20 year old rototiller with a Briggs 7 hp engine
