  • can't get glow engine to start

    I bought a OS 61 glow engine. Cleaned it, New glow plug, New 15% fuel. try to turn the Prop and it gets stuck after a few turns. Think its something called Hydrolock. Should I turn down the high speed needle? Or is something else wrong? No sputter out the carburetor port.and it never starts.

    Google the carb settings for your engine always start from closed and adjust open both high and low settings. Its flooding if its hydro locked. I found this
    Here are the ballpark control settings, from the 7M carb instruction sheet:

    1. Main needle 3 turns if _not_ using muffler pressure or 1-1/2to 2 turns if
    using muffler pressure.

    2. Mid-range two turns open.

    3. Idle mixture at mid-travel.

    O.S. recommends that the mixture controls be adjusted in this order: idle
    first, then mid-range, then main needle. (FWIW, I've never had a problem if I
    set the main needle first, then idle, then tweak the mid-range after hearing
    the engine response in-flight.)
