I have a 92 Black Max 135 thats was running great on auto pump fuel and i changed to premix 50:1 because the pump wasnt pumping oil and now fouls up plugs when idling around. Compression i all 120 and motor has done 950 hours. The problem only started when i went to premix. Can i swap to Optimax J Type Plugs without any harm?

Thanks in Advance

Yer mate went out crabbing the day before, started it the next morning low oil alarm it has a new float switch on top tank new thermos last season new plugs last season pulled pump senser it stopped beeping pulled oil pump feed off no oil coming out. Done this all on 50:1 mix. I may have over oiled slightly. I dont know if this would be enough to foul plugs. Goes great once i get above idle just annoys me when im idling around pulling my crab pots.

Cheers
Dave
