i know of 2 other engines that took some fuel to run in properly.
this is why im thinking i have a problem with this engine. its supposed to be for Nats, and i really cant put faith in it now, knowing it took no time at all to run in.
when i say that, my M3T i have run in using same fuel same amount of fuel, and completely different engine as far as pinch is concerned. the M3T needs more run in.
