Replaced coil twice and replaced ballast , sometimes and only sometimes it will start if u have it in drive and u hold down the switch in the start position and will even Rev up but as soon as u let off the switch in the on position it will die and will not start again a couple of time I have made it spark through the coil only when u switch the ignition switch off and 1 quick spark from the coil. It's a head scratcher no one has been able to figure it out yet I'm even willing to talk to some one about what has been done if it would be any quicker to figure out 205-368-6591
