sounds like you need to adjust the carburetor.

Have you checked to see if the carb float is sticking of the needle valve is sticking open? I had a Cub 154 that acted that way when this happened? That or a plugged up bowl vent.

if you have gas and its not the float and your carb is adjusted check to be sure your point gap is correct.file them and set them to around.016 to start with

:ditto: Black plugs is a sign of too much fuel or weak spark. Does fuel come out the bottom of the carb when you shut it off? If so, recheck the float (sometimes you have to set it a little lower than spec) and make sure the needle valve isn't sticking.

Sometimes you can tap on the carb and free up the needle valve or float. This may work for on the spot but the underlying problem will still be there and need to be corrected.

Can needle valves on tractors get grooves worn in them like the little B&S engines can? If so could that be a problem? Need to clean them plugs up.

Ryan, the same can happen with tractors, the needle valves get worn and need to be replaced periodically. It's usually a good idea to do a full carb kit while your at it. That ensures you seal up any vacuum leaks that may be there with all new gaskets and seals.

Not sure if you have Tractor Supply Center or something like it up there, but they might carry a kit; otherwise it is the MF dealer.

You should be able to getr a kit from UAP/NAPA or any good auto parts store. You'll need to get the model # of the carb. On a MH it will be a "Marvel Schebler" TSX _ _ _ . That info is on a brass tag on the throat of the carb toward the opening.
