My Super M sat for over a year without running. After I put some bearings in the trans I had trouble keeping it running. It would run at high speed but not idle. I took the carb off and cleaned all of the passages, set the float, put a new needle and seat in and even had the manifold resurfaces and put in a new gasket. When I first put it together it ran fine. Last week when I used it to pull some logs it started surging at idle. It ran ok with the idle screw in all the way. I had it running yesterday and it started surging no matter what I did. At about half throttle it will smooth out and run fine. Any suggestions?
