Are you running the engine without a cowel so it gets enough air to cool correctly? Usually the reason a engine quits in the air is lack of fuel. I might change out the carb to one you know functions correctly.
Hey Taildrager,
Thanks for your tips. It must be the carb that ZDZ is using. The needle valves are not functioning properly. I'll change the carb to a brand new Walbro and I'll keep you guys posted.
