DDog- I have been at this morning. I did some plumbing work and replaced a fueler valve with a brass T. I believe the valve was bad and adding to my problem. I ran the engine a few minutes ago. IT RUNS. Top end is Ok. Idle is not. It seems to load up and want to die. Add throttle and it is SLOW to return to max power. Regulator problem maybe??? There is no low end adjustment for this engine.
