Took my boat out Sat. Started right up, idled fine. After about 1/2 hour, turned it off. Couldn't get it started for about 20 minutes. I took the plugs out, and they looked dry. I got it started finally using ez start, and the same thing happened a couple of more times when I stopped and then tried to start it. Took the carbs off, took them apart, looked perfect, no gum deposits or crud. Took the low speed idle jets out, blew carb cleaner through everything, everything seemed fine. Changed gaskets, o-rings. If this doesn't work, any suggestions on what I should check? I took the fuel screen out, and it looked clean. The engine runs great at all RPM, just won't start when hot. It's got new fuel I bought yesterday. The compression is 100, 110, 115,115.If the timing was off, would it do this. It starts right up when cold.
