RE: DLE 30 high power with throttle closed!
Thanks for all your ideas,I noticed that the butterfly spindle had some end play so I pulled the motor and had a good look.The butterfly was loose! At high openings it was jamming against the carb body/ventury...blipping the throttle was enough to un -jam. Re-tightening the valve (with locktite) sorted the end play as well. Icleaned the carb and the filter. I am hopingmy problemis fixed. (with no damage to the servo) I am amazed how clean this engine is externally and peeking in to the crank case. (compared to glow motors with the same use/abuse) I will post the result tomorrow.
