I've got a Gravely 8163T with the B43M engine. It has a single barrel carburetor. One cylinder is working lousy, runs wheezy and makes a fair amount of black smoke. The other cylinder runs real good, burns clean.
It is a single barrel carburetor with coil. I have tried two carburetors and two coils, same result.
Is there some sort of vacuum related problem here? Not enough air to complete combustion in one of the cylinders, it appears. Compression in both cylinders is around 120 pounds.
Is it a spark plug problem or lead wire problem?
This has baffled some of my engine buddies and we have not come up with a solution.
Waddya think?
