Perhaps these engines are individuals, Mine works perfectly with full open on the carb, although I have done some modification to the inlet lines to get a better flow. Perhaps that has some positive effect since I can idle below 500 rpm without losing the lower cylinders, and yes, the carb is then fully closed. It seeps enough air through the small hole in the butterfly.
