Dave:
The engine loads up with fuel during 3/4 or less throttle when flying and dies rich. I have to run full throttle to clean it out. I have the low speed adjustment as far out as I can and have experimented with screwing in the pressure ajustment screw. Have been waiting for your response prior to tring again. Also, on my question #2, what is the correct plunger spring direction, large end versus small end?
Thank You
Paul
