Tecumsah snow blower engine running rough

I have a Troy-Bilt snowthrower with an 8HP Tecumseh Snow King engine. The engine is running very rough - surging from very high RPM, down to where it just
about cuts out. It's also consuming a LOT of fuel. When the auger is engaged the RPM drops significantly, but this doesn't happen when the wheels are engaged. I've tried replacing the spark plug and have changed the fuel. Any other hints from the forum?

Hello saugusta. Welcome to the Do-It-Yourself Web Site and our Small Engine forum.

Based on the problem description, the engine is flooding from too much fuel. There should be some black smoke visable from the exhaust. If that is correct, the carb needs to be cleaned out and a new carb kit installed.

If such is not the case, chances are the carb is not allowing enough fuel causing a lack of fuel to get into the engine. That will cause the engine to bog down under a load and or stall or die.

Reading any existing question which indicates an engine running problem, you will find additonal helpful advice, suggestions, including solutions to correct the problem.

Most likely I haven't covered all of the possibilities. The other resident small engine service and repair professionals in the forum may be able to offer additional suggestions, advice & help.

Check back on your question several times over the next few days for additional replies.

Hello saugusta!

I agree...you have carburetor problems. If it is flooding, make sure the choke is not closing, make sure the float is not full of gas, and check the carb adjustments. It may also be leaning out. If so, remove the float bowl and clean the bowl and the bowl nut...(it should have tiny holes in it that could be clogged).
