SN 0t987569 Motor can run at top rpm and drop a cylinder in and out but not enough to lose speed? new plugs, checked connections, compression is good will not stay out enough to diagnose. Resitor plug caps look good on a meter.
I know it could be coil but the motor has around 300 hours on it. Has anyone had component failure with this few hours?
Is there any connection paste that will make the wire conections conduct better. Any help on this would be appreciated.
