    75 ax dies out at mid range

    After about 75 flights on my 75 ax it runs good on the ground from low, mid range, and high.

    Problem is, after it's in the air it flys ok at low or high but dies out at mid range even with a new glow plug.

    any help would be appreciated

    RE: 75 ax dies out at mid range

    Usually, if the engine dies at midrange, it's too rich. That can mean that the low-speed needle's a bit on the rich side. It could also mean that the fit to the piston/liner is starting to go bad, though idle usually goes bad first. You may want to check out the entire fuel system to make sure it's clean and unobstructed. That's about the best we can do without our seeing the engine and running it ourselves.
