I have a Farmall Super C from 1953 I believe and ran into a problem a few years ago when the tractor started erratically misfiring (sounds like its about to run out of gas) so it was parked for a few years when we recently bought a new zenith carb to solve the problem to no avail, still misfiring. It was also surging bad so I pulled the governor housing off and replaced a broken adjustment spring and the surging stopped but still misfired, cleaner the condenser points and put in new plugs but still surged, could it be ignition problems or compression problems? The tractor fires right up most of the time which leads me to believe its not compression, and a cant find any diagrams on adjustments for the zenith carb, I see the screw on top for the float height adjustment, but there is also a bolt right across from the fuel inlet fitting, is this for air or fuel of just to hold it together? Could there be an air leak somewhere I dont know about? Help would be much appreciated, thanks. Logan
