Optimax 200 (2004) - starting problem

[Ben1980]

Hi guys,

Hoping someone can shed some light on this starting problem...

when the engine is warm and I turn the ignition key the starter cranks over just fine however the engine won't fire until I release the ignition key from the start position, the second I release it the engine fires and runs fine. Very occasionally when I turn the ignition key and the engine is warm nothing happens at all, but if I leave it 5 mins or so it will be fine again. Starting from cold always seems to be fine.

i don't think it's the battery as the voltage gauge reads between 12.5 and 14, and the trim motor always works fine.

Any ideas much appreciated.

Thanks
Ben

Do need to load test battery, voltage to engine when cranking needs to be 10 volts or higher to run.
