I have a Fuji 43cc with a magneto ignition system. I bought it mounted on a plane at an auction so I have no idea of when it last ran. I have tried all of the traditional starting sequences with no luck. After many attempts I got it to run for about 10 seconds one time but most of the time I can't even get it to fire. I put a brand new spark plug in and tested the spark several times. I have even tried spraying starting fluid in the carb and got nothing. I would think that even if I wasn't getting fuel into the carb it would ignite the starting fluid. I'm out of ideas so any suggestions would be greatly appreciated.
