All you are doing with the finger test is checking to see if there is any compression at all, eliminating the possibility of a holed piston or broken ring. A proper compression test requires a compression tester. For your purpose here, which is to see if you blew the top-end, blowing your finger off the plug hole is a sufficient test to determine that there wasn't a catastrophic melt down. Just don't stick your finger inside the plug hole, if there really is some slag sticking up from the piston, you might get it jabbed into your finger.:eek:Originally posted by Blinkme7182
what else should I do to check for compression besides put my finger over the spark plug hole and see if it pops off when kicked over...if it doesn't then does that mean I need a new top end, or...?
