Mark,
Thanks for the break in info. Unfortunately I do not have a bench to run in the engine. I'm having to go the most cost effeciant way going with this expensive combo set up (Expensive to me anyway). I planned on running about 3 tanks (16oz=1 tank) on the ground at full throttle with a rich needle setting as per YS recommendations somewhat. After that, I will attempt my first flight, again having a rich needle setting, and keeping her at, or very near full throttle as much as possible, flying the plane in patterns with no verticle work. I appreciate your info on the regulator setting, for I have heard horror stories of others that have lost the setting, and after have had nothing but bad responce for the YS engine.
