Hi folks, I have a bit of a prob with my os 32 engine on a Caliber 30 heli.
It starts fine with plenty of oil and smoke coming out of muffler, but when I disconnect the glow plug the engine dies. I'Ve no idea where to start, I've leaned out the mixture screw from 2 turns to 1.5 turns to 1 turn with no joy, the engine still cuts out when plug is taken off. the response from radio is good, it revs up fine with plug on. Any help would be a great help.

Cheers...P
