Michael,
Yes the gap on the plugs is .022. My engine is still running great. I do not have it on any plane at the moment because I just started building the 91" Gee Bee Model Y sportster that is will be moment on. I have one question. When your choke the engine and spin the prop do you see gas being pulled from the tank to the carb? I made a attachment for my HD starter to go over the bolts on the hub to turn the engine over. It is very hard for the carb to pump full to the engine when the diaphragm is dry. That is why a starter is the best bit on a new engine. Good luck and keep us posted.
