I have a 1990 Johnson Gt 150 that won't start cold without cranking for an extended time. Once it does start in runs great all day. Just for grins one day I heated the motor with a torpedo heater for 20 min. and it started right up. Pleas whats going on?
Thanks for any help P.S. I forgot to state that there is no spark when cold. new plugs , new coils. When it does start it starts on 2 cyl, then picks up other cyls.
