Hi

I have an issue with my Griffith 500. When the engine is cold it runs fine. As soon as it starts to get warm it begins to stutter badly up 3500 RPM - it then won't hold idle either - it drops to 500 RPM and barely stays on. Above 3500 RPM it runs fine even when warm. (have left some black tracks on the road when it suddenly kicks in :- )

I have a fairly new coil and ignition leads - I cleaned the stepper motor - checked the distributor - checked oil pressure connector. Any ideas of were to check next are more than welcome

Cheers,

Dan
