Tecumseh 8hp carburator leaking fuel.

First I thought it was the float bowl gasket, replaced that and now it looks like fuel is leaking out from above it, where the choke is. Raising the float does completely shut off fuel flow. Not sure what the problem is.

My guess is that the fuel float is sticking? Should I spray it all down with carb cleaner? Any other problems it could be?

take the float out and shake it. It may have a leak and has fuel in it. If so it will not rise enough to stop the fuel flow. If it doesn't have a leak it may need to be adjusted. If i remember correctly with the carb upside down there should be an 1/8" gap between the float and the carb body. you can use a 1/8" drill bit to check it. carl.

It's bigger than an 1/8th. 17/64ths I think. It's been a while. The float should be more or less level when the needle valve is seated.

Check to see if the float is leaking and replace the needle and seat (small carb kit with the needle, seat and fiber washer is $10.00 over here in Canada, it should be less in the US.

Had the carburetor rebuilt. Purring like a kitten. It's my first snowblower, and I have a miserable driveway. I have never been so excited for winter in my life. Bring it on!!

Did you rebuild the carb or did you have a shop rebuild it for you?
