Odyssey FL250 / Re: 1981 FL250 Won't Start When Warm

The manual says spec compression is 129. I see what you're saying though. Maybe 125 PSI is still enough to make it start, but 119 isn't enough. I just wouldn't think that would be enough to make a difference.

If it is getting too much fuel, any ideas why it would only do that when warm?

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.

I'm not super familiar with the Odysseys and Pilots, so forgive me. I have a 1981 Honda FL250 in my shop and I have it to the point where it starts and runs great if it's been sitting for a while. But if I take it out and ride it then shut it off, it refuses to start. Seems to only happen after it has been running for a bit. It's acting like it's getting too much fuel. Choking it does not help. I'd appreciate any advice. Thanks.
