Not to fan the embers of a dead fire, but, let me get this straight, David built you a carb from miles and miles away and it ran well? From just talking about the build? And your complaining on a tenth gain when you did your TQ on your engine present and in front of you and not how many miles away???
"Then my home built thermo picked up 1 tenth over his..."
The one thing that the TQ drives me crazy on is the rear air door and what you have experienced. The A/F changes but the slip does not. You must be running at peak and restricted heavy.
