Leaky Float bowl

I have an older Sears 20 inch pushmower with the 4.5hp Eager 1 engine.It leaks gas from around the float bowl.I have disassembled the bowl completly and once you start up the mower it begines to leak again and it leaks lots!The rubber ring gasket seems ok but I am at a loss as to what is going on.
Does anyone know what the problem could be??

No small engine guy...but if it's leaking where the gasket (O ring?) should seal it..you need a new gasket.

Learned that a long time ago on hot rods. Rubber valve cover gaskets were nice when you needed to pull the covers often...but eventually they leak.

The fuel shouldn't even get high enough to leak out of that gasket. The float/needle is leaking. Take the float off and shake it near your ear. Hear something sloshing in it? If so, that's the problem and you need a new float. If nothing sloshing, then you need to service the needle and seat.

Hello skane1,


If the carb is leaking that bad you likely have a faulty float needle valve seat, You can get part #631021 which will come with both the float needle and seat then replace the bowl seal as Gunguy45 mentioned with part #631028. This should solve your issue.

Just in case you need it, Here's a carb clean/service "how too"..... This may not be your exact carb (no numbers posted) but their all basically the same; Disassembly, Cleaning and Repair of Tecumseh Series 9 Carburetor 632747


Good Luck


[EDIT] Mr. Cheese beat me to the punch but I'll leave this info up.....

I disassembled the float bowl and gasket etc very carefully today.After everything was put back together the leak has stopped.How tight does the float bowl need to be??I put it on just snug and everything seems ok now.I might buy the parts you suggested just in case.
Works pretty well for a mower that was on it's way to the landfil.
Thanks again for the great advice!

Good to hear it stopped for now.....

If it's not leaking that's plenty tight enough, They don't have to be cranked down really tight.


Good Luck
