fleetwin, you gave me a thought… I measured the nozzle well (.313) and the carb casting (.311) , so only .002 clearance. So I guess what happens is that what ever gas enters the well thru this clearance is unmetered and the high speed needle simply meters the balance needed for high speed running. I wonder if the machined surfaces on the carbs that need the gasket are engineered for such a close fit? If not, might be a way of being able to tell if a gasket is required.
