370 main.
leakdown tested. no drop in pressure.
stock comp, hadnt put the new dome on yet. running 91 octane, place that sells 110 was closed.
it ran great all week, then pulled this crap today. did a 2nd-6th pull and half way through 6th it pinged once or twice then it died and locked up. i thought it may have been hot, so i let it sit for a few mins then tried to start again and you could tell there was little to no comp.
pulled the plag and it was covered in specs for atmoized piston. im assuming ringlands like the last motor.
im starting to think that carb/pipe is cursed.
