Okay.... this thing had been running great. I put my own oil in when new and changed it at 50 miles, or so. The gas is 91 octane and treated. Now, it cold starts fine. When it warms up (I guess the electric choke is kicking off), it barely idles or dies. If it is idling and you give it the gas, it dies. The petcock manifold thing (is this a vacuum operated fuel pump?) is getting plenty of gas to it. I have a spare so I swapped it out... no change. I put an NGK spark plug in (gapped to .025 in)... no change. Any ideas?

You nailed it on the head. I did it twice. The first time, I don't think I was paying attention and set them at .005 inches. It idled much better but wouldn't take the gas. I did it again at .05mm and that did the trick. It is also quite a bit peppier now. I have to say that the adjustment was easy and I like how easy it was to get the plastic off to gain access to the head cover. Thank you very much.
