Checked compression. Each reached about 190-200, but 1 and 4 jumped up there after a few cycles, whereas 2 and 3 got there a little quicker. I've never done a comp. test before, so I'm not certain what's normal. Also, should I rev the engine while checking compression?
It sounds like you're doing the compression test with the engine running - is that correct?
