Default RE: Motor surging

ORIGINAL: BullardRM

I have a new motor that has approximately 10 gallon through it. Just in the last two weeks it has started surging at mid throttle. Idle is great, top end is greatjust in mid range. Suspect I need to adjust one or both needles. Don't care to go guessing. Any previous experiences with this would be greatly appreciated.
Run the engine on the graund and check your throttle servo to see if it is ocelating causing the engine to surge.
A fellow at my flying field had the same problem and we discovered his throttle servo was causing it.
