I picked up a non running complete 70 lp a few weeks ago. It was lightly set up but within an hour of some diesel in the cylinders and it was free. In trying to get it running I did a compression test and found one cylinder at 70# and the other at 0. When I took the head off, I found it had not to long ago been overhauled and had .45 over pistons with no ridge at the top of the cylinder. I popped the valves out and found one had visible pitting on the seat so took the head to an engine shop. On a visual inspection, he found cracks in both cylinders, on the raised brow above the intake valve. My question is, is this common, why in the world would it crack in both cylinders above a relatively cool valve, and what can be done about the cracks? Thanks in advance.
