Having issues with my 632 Bobcat. Starts right up but when it warms up, it flutters and misses. I have tuned the engine up with new Points, condenser, cap and rotor, plugs and fuel filter but still doesn't run smoot like it use to. I set the points at .025 but not sure if that is correct. Does anyone know for sure what the points gap should be? It also seems like the governor doesn't open up. Any suggestions on what to check next?
