Spark plugs, wires, coil, and starter. ( 86 140 hp mc/with a mc carb) I also not sure about the acc pump, but I do know it was replaced with the rebuild...

(40mph at 5000rpm) (I didn't stay at that speed because it only has a 4800 limit)"

"I'm thinking it is the acce pump. I know it was replaced, but I don't know if their is a way to change setting or is just installed?"
