I just took my air command 447 out today. I tried to run it up full throttle on runway and it just sputtered. I pulled off, then ran it at half throttle for a minute and it ran fine. It starts and idles great. Is it the float needle/seat or air/fuel mixture? The motor and carb was rebuilt with 30hrs now. Anyone with same problem and how to quick fix?
