Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I recently aquired a Snapper i 422, it has a 4hp Tecumseh engine. The model number on the snowbloer is i4222e if that would help any. My question is about the carb. When I put gas in the tank and turn on the shut-off, gas starts coming out of a pinsize hole in the side of the carb (see picture).  When I push the primer gas shoots out of the hole. I'm pretty sure this isn't supposed to happen. any suggestions on why it is? I looked in a small engine repair book and a carb that was like mine had a discharge hole, but I'm not sure if thats what the hole on mine is. Also, can anyone think of any way to get this fixed? The pictures are kind of blury, but my camera doesnt work very well that close up. By the way, the only information i could find on the engine is that its hs40 you can google it if it helps.

     

It's an atmospheric vent hole. It must be opened to the atmosphere to prevent creating a vacuum. The reason fuel is flowing out is because the carburetor float inside the float bowl is not shutting off the fuel when the engine is stopped. You must drop the fuel bowl and clean it. It may have sludge or other stuff in there. Before you start the engine, be sure no fuel have entered into the crankcase. It will dilute the oil protection.

Jake nailed it. However, the main well tube is ALSO clogged, which is why it isn't dribbling out the carb throat area. You will need to remove the bowl nut (main jet) & run a wire up thru the main well tube - it extends into the carb throat. A GOOD carb cleaning is DEFINITELY in order here...

Thanks, I'll do that.  I just want to get it ready and running for the first snowstorm (which I hope will be soon)  ; )

I'm trying to get it back to new, and the first step is to get the engine running. 

By the way, does anyone out there own a snapper, that could give me some info on it?

all I know is that it has a 4 horsepower tecumseh hs 40 engine on it, and that the model number is i4222e.

Does anyone know what year it might be from? The guy i got it from said 7 or 8 years old, but it looks a lot older.

Thanks.

Adam - These are indeed older machines, at least 10-15 years old. The 4hp WILL move snow, but you will have to work more slowly with it when the snow is deep and/or heavy...

For all of you who wanted pictures, here they are.  I hope this helps...

The Snapper, yeah i know she's a bit rusty,  but its only surface rust...

The Toro, still starts on the second pull!  (even without the primer bulb)

I hope you like them, because copy and pasting all of those pics from photobucket took FOREVER!!!!

I LIKE 'EM!!! GOOD PICS!

That Snapper is a nice little machine! Why don't you treat it to some sanding, then a few coats of Red & white spray paint? She'll look like NEW!

LOVE those little Toro's - a $2 primer bulb will square him up! Just be prepared for the "fun" of removing all the cowling to gain access to it...

Marty

Actually, that was next on my list. After I got the engine running (hopefully today). I was going to sand it and paint it so it would look nice.  I'll take some pics when its done.

I was also planning to get a new primer, next time I went to the hardware store for some sprk plugs and things(most likey also today). I don't think it will be to difficult to get into the cowling on the Toro. "I'm experienced", I've had to do it on bothe of my other single stages. The MTD, when the recoil starter broke, adn the electric start wouldnt engage, and on my old Toro S 200, it was my dads, dads, snowthrower, which finally konked out after all these years. Both times I had no trouble. 

Glad you enjoyed the pics!!

Hopefully the bolts/screws won't give you any problems. Many I've serviced end up having the fasteners BREAK upon removal. Drill out, retap, new screws. Makes a simple repair a pain in the tukus...

Then I guess I got lucky, I only had to remove the "dash" cover, and used the spark plug access cover to get to the bottom of the primer.  I ended up just prying it out with a screwdriver, becuse i couldn't get the little tabs on the back to squish together.  The OPE shop I usually go to was closed, and the hardware store didn't have it. So today I'll have to go back earlier adn get the primer.  Also, I have some numbers that I found under the tarter switch(as suggested) but, I can't fiure out what they mean... They are: HS40-5552L SER 901T0  I'm pretty sure that I copied them correctly, BUT, the 9(bolded) might be an eight.   The book I got from the library doesn't show what they mean.    If anybody knows, it would be appreciated.

Thanks.
