Question about a 2 stroke engine...
I was recently given a old airplane from my dad. This thing has probably sat for about oh, 10 years. I just got a new radio and receiver for it. I am just having a little problem Fine tuning the engine. I know there is a high and low needle valve. one which controls fuel and the other controls the air.. My question is I have it lean enough to where it almost shuts off if I turn it down to much but I am still getting oil out the muffler. Second when does low needle valve come into play? I can't really rev it full and get good response from it. Any info would be good. Any advice or a thread I missed?
