RE: 120 decreasing rpm
Petec you are the man!! I just now tried the needle valve out of my 120 in my buddies that I have been working on and it runs great at the 1 1/2 turn out setting, even chokes and starts to die when I start to lean it out more then that. When I compare the bad one to mine it is about 1/16- 1/8 in shorter and doesnt have as sharp of a point as mine. I have had to change quite a few parts to find the problem but at least the engine is in like new condition. I guess another order from central hobbies is in order.
thanks for all the help.
