How did this motor run for you last season ?----Do some simple testing / inspection and post answers.------Inspect fuel pipe INSIDE the tank.----Post actual compression values.-----Does spark jump a gap of 3/8" on both leads?-----Is there a pulse from the PRESSURE port where fuel pump mounts , yes or no ?-----Is water pump impeller in good shape ?---Checked flywheel key ?----Checked for plugged exhaust?---You could have an issue with a reed valve ( broken , stuck open with debris )_ and that can easily be checked.----I am 4 days driving away but repair these issues all the time.----Picked up 2 of these motors recently , for parts / rebuild ?-----These motors are easier to repair than some new motors.-----Too bad local shops refuse to work on a motor that appears it should be able to run like a new motor.----Grandson is coming here this summer , but I might still be near SUNDRE later on this year.-----Don't throw this motor out !!!
