I have been having some problems leaning out the 3.3, i am not new to nitro engines but, i am newer to car engines mostly boats. I have the 3.3 about 4 turns out in my jato. For me i think that is alot, when i try to make any change to it by leaning it out more, it wants to bogg down or cut out at full throttle???? The engine is fairly new, with about 1/2 a gallon of 20% ran through it. In my boat motors i can lean them out to 1 1/2 to 2 turns out with no problem. So my question is?? is this normal or am i doing something wrong?? It seems like the stock air filter is kinda restrictive, if u take it and try to blow through it, you bearly can. Could this be the problem, idk its just a thought??? thx
