Yikes! That sounds like a really fun surprise! Glad you are ok!Engine compression was pretty much the same as when I built the engine after break in. I did a leak down test on #1 and it was only 2% at 95 psi. Then my air compressor took a crap and that was the end of testing tonight. I tried my uncles compressor that he got used and it shot a fireball out of the plug that hit my leg. My leg is fine but obviously there is some issues with that compressor. That was my clue to call it a night.
