Hard starts, long crank time before the start, rough idle, and loss
of power can be caused by using the wrong type of oil in this motor.
With the engine off, remove the oil dipstick and inspect. If tiny
bubbles are present, then the oil is foaming and unable to maintain
proper operating pressure in the high pressure oil system.
