Mine AGM 30 doesn't start after the unfortunate landing on my plane with out one wheel...forgot to off the engine ignition , before touching the ground....)-:
Visual looses are: broken woden prop and the spark cap was dismantled only. Try to start the engine, but after a few flips it's only pops...
The spark is O.K. May be some more serious problems than the carb tune???
My Dynaflite Superdecathlon was full of power with this one and only a few dead sticks it had at all last year season.
