Hi to you all.I am George from Greece and i have a problem with my os fs 120s e engine.Sorry if my English are not good!!

The engine has flown about 10 flights of about 6 minutes per flight and it still stalls at low speed.The engine rpm that does not stall moves the plane.Many others have the same engine and works perfect at low speed.On the air the engine has never stalled.When i land and move it to the parking area it stalls and when i trim it a little up the engine gains rpm but the plane moves.My plane is a 120 class p-47.

Thank you for answering!!!!!

Hi!
Sounds as you run your engine a little too rich at low speed. Try turning in the idle needle some.

Hi George,

I think I know you. I am Stelios and I am flying at "aldex" club. Is that you?

As for your engine, I think you should lean the low speed needle 1/4 - 1/8 of a turn at a time.

Yes it 's me!!!The valves did not have the appropriate opening!!They were too close.We opened them a bit and it works better.It holds low speed for a while then it starts smoking and stalls!I suppose it needs a little leaner the low speed needle! I will check it on Saturday and will see if it works fine!!

It surely will.

I can help you if I am at the club on Saturday.
