Help!
Problem with Dle111cc Idling when in air.

Hey guys I just maidend my new sebart 100cc yesterday..It flies great...But having problems with my engine. As I did the maiden yesterday I flew her around and trimmed her but then I noticed as soon as I close the throttle from quater throttle and downwards then my engine sounded like it wants to die and when I give throttle after that then the engine works..but the funny thing is when she is Idling on the ground then shes perfect..but in the air its not. and i let the plane idle higher and not too little,its the first flight with a new engine..I dont know whats wrong..please Gents I would be so happy If you could help me.

Make sure you have plenty of exit air. If it's fine on the ground and worse in the air it may be pressurizing the cowl in flight. Yaks and Sukhois have that huge opening in the cowl and usually a small one underneath. Just not enough! Good ratio is 3:1 exit to entry. If you've got a canister tunnel, open up the vents to equalize that pressure and you should do fine. Good luck!

sounds like the low end is lean. Engines lean out a bit in the air which sometimes causes engines to run great on the ground but run poorly in the air.
