i would start with a 155 and go from there. also if u pm GPracer2500 im sure he will help u out, he helped me out and knows what he is doing when it comes to jetting.

Start w/a 155, also step up to a #40 pilot.

40-45 pilot, 155-170main seems to be where most fall into. Search for some threads from GPracer2500 on jetting. He and 400exstud are two guys who can give you soem really good advice.
