Problem - cannot get motor to idle (2400 +/-) w/o turning the idle screw to full rich. Throttle between idle and half throttle is rough when held at a constant. High speed is fine. Using CP 30 heli fuel and located at altitude of 5200'. Checked for fuel/air leaks and could not locate any. Attempted changes to regulator setting and changed out glow plug w/new with little help. Engine has only a half dozen flights total and a couple after being repaired at YS after pilot error. Any ideas.
Thanks
Mark

If this is just back from our service dept., I would call Rich Verano asap at 775-782-4562 during business hours 9 to 5 west coast time.

Before doing this you might go to our web page and go through the running instructions. It may cure the problem.
