Speaking of rear mounted carb!!!!! For those of you that have the problem, how close is the carb to the firewall? Does it protrude through or do you have a large enough hole in the firewall so that air flow is not disrupted?
Again, I had this problem @ about 2 gallons but after leaning the low end it pretty much went away. Never cut out in the air though. Only on the ground when you grabbed the tail or made an abrupt turn at idle.
