I have tried fireball hot plugs that have no idle bars. I also tried two different glow plugs with idle bars, but I don't know what brand or heat range they were. I have always used the fireball hot reg. plugs with great results. This is a new to me used engine, maybe it is some other problem. But it works fine until I pull the plug wire. I have tried 3 different plugs with the same results. So maybe there is some other problem.

After it dies I can reconnect the plug wire flip it and it starts right up, but once I remove the plug wire it will run for a short while and die. I am running it at full speed for control line. It runs great but before I can pick up the handle it dies. I tried it atleast 12 times. I thought maybe something was lose in the heater filiment, but I can't imagine it happening to every plug I put in.

Thanks for the imput
