My problem was the carburetor was starving for gas on hill pulls.
Max, I know you sold it. But when my switch blew off of the oil pump, I lost the pump in the tank. MH ran fine on the flats but when it came to the hills I had to easy foot it. Once the switch was replaced no more problems on the hills. I wonder if your tank pump was bad?
