Thanks for the replies, guys. LiveWire, I replaced the fuel pump, so I don't think that should be an issue. As far as the compression goes, I tested it both warm and cold. When it was cold, I had about 125 PSI. When it was warm I had about 119 PSI, and it held the compression fine. Is that enough of a drop to make a difference?
Marty, it has good spark when warmed up and cold. The plug was dry when I pulled it out after running. I tried your trick to make sure the carb bowl was full and still nothing.
I forgot to mention that when I initially try to start it after shutting it down, it fires for just a second. Then it just dies and won't fire at all until it cools down. I have also noticed that it will start fine once I drain the carburetor and pull it again. But that may be just because it has enough time to cool down while I drain it.
I'm starting to lean towards the compression being just low enough when it gets hot. I wouldn't think 6 PSI would make that much of a difference, though.
