One more fact - the engine diesels for 1-2s after shut off. We tried 3 different plug heat ranges and no difference. Also minimizing advance even to 0/20* does not eliminate it. Idle is 900 rpm.




Automatic? If so does it diesel if shut off with the trans in gear? If not consider installing a idle solenoid, with that done the standard idle screw is backed out completely & idle is set with a screw touching the plunger of the idle solenoid.. That way when power is shut off to the solenoid the throttle closes completely...
