Won't idle when warm

[snm720]

I have a late 70's 90 H.P. that runs great. It starts easy and goes like a champ, when the motor is cold! After it gets warm, it gets tough to start, and when it does fire up will not idle at low RPM. Please help!!! I know it must be something simple, and I'm sure that someone out there has the answer.

Thanks for the help,
Mike

Re: Won't idle when warm

You need to check the ignition system when hot, stator, switch boxes, trigger and coils. Need test specs from manual.
