Hello there. just bought and 1986 craigslist special with a mercruiser 305. During my sea trial I heard the engine backfire a few times so the first thing I wanted to start with is a compression test. I've also been having a problem with the engine dying when I put in reverse and then it won't start back up for another couple of hours. Anyone know if it might be a case of a bad carburetor? Well anywho here the test results. I read on the innerweb that any variance below 15% is ok but I still can't help but wonder why I have one high one and one low. On the low one I put in a little oil into that cylinder and it came back with same results. Are these numbers acceptable?
