I have an 155'5 IC model 31A607; The engine will not keep the battery charged, Checked the relay and it's pushing 13.9 volts and the battery is new. If I jump start it from a car battery it starts. Otherwise the engine runs great. It seems like the motor has very high compression. Are there any recalls or notifications pertaining to the high compression problem.

Hi,
Calls for a valve adjustment to 0.006" See:
