RE: Giant Top Flite P-47 Thunderbolt frequent Engine failures
that is too nice a bird for a balky motor put a zenoah g62 in it you will be happy. i never touched the needles in 3 years. Velocity stack may help. what i do is have a hatch right over the carb thats magnetic. When flying i remove it to work the choke and fly. You cant see the small hole in the air and the carb will get enough air
