Hi Lee The carb requires a cold air source, you are using heated air in your cowl, this will cause the mixture to richen up. When you run the engine with the cowl off the carb is getting cool air. Before I sealed my cold air source to the carb the carb inlet temp was running 145 F. Yours will be even higher if no cold air is getting to the carb.

Yes a little scarry, but yes I did remain calm. As I was driving to the cruise ship, an idea came to me re: the inlet of air into the carb. First I have a POSA carb (yes I know I know) I runs great on the ground, low and high speed. The high speed RPMs could be higher. I was thinking this was caused by static forces. Now back to the problem, I have a gap of about 1" 1 1/2" from the cowl to the inlet of the carb. Does anybody think that once I got up to speed 90-100, a pressure or/ low pressure situation could have occured in the lower cowl, causing the flow of air to the carb to have effected that mixture? The motor never quit, but started to run really rugh and an incredible amount of power loss.
