Expert:  Wayne replied 1 year ago.

Thank you for that

there was no way for me to know, the oil was diluted with gas

Yes time to rebuild the carb

Wayne thanks for you're effort but not sure how you get a stuck piston when the engine turns over w/o a broken rod which would give a dead cylinder (no compression) not to mention the noise associated with the broken rod. I only found the gas contaminated oil myself while doing the compression test. Bot***** *****ne is the oil shooting out the carb was a result of too much pressure in the crankcase do to the gas/oil mix blowing it out the crank breather filter. So I guess the answer is you're response did not help at all.

OK, Just glad you have it going

when I put piston stuck, should have used a (,) stuck rings , not piston

which gives crank case pressure
