Need some advice on the Marvel Schebler carb on my MF135. I rebuilt the carb recently but the engine still has a tendency to sputter a little as before. The idle air adjustment has to be screwed all the way in to get a smooth idle, however, I have to screw it back out some for it to run half decent under full load. Engine sputters at idle or at full load (or both) no matter how I adjust the mixture screws. Just can’t get it completely adjusted out. I have checked for possible air leaks around the carb and intake. Partial choke has no effect. Engine has new plugs, points, condenser, dist. cap, wires and coil. Good fuel flow to carb. What am I missing here? Is there something else I need to check? It also seems to use too much fuel. Thanks for any advice.
