I rebuilt the carb, new everything (not just the gaskets, etc). Same problem. Tinkered with everything, took that carb out and put it back in a dozen times. Then I read that the Main Jet and the Pilot Air Jet are the two that control the idle mixture. I went back to the parts diagram and discovered that I had interchanged these two jets (they fit in both holes). I wasn't reading the parts diagram correctly - 30 goes into the side of the carb and 28 is under the diaphragm. Anyway, thought I might save someone some time by posting this. Oh - and I'm new to the forum.
Thanks.
Welcome gzvirgin. Good catch concerning the jets. And yes you will surely help the next rider with carb problems due to a mix up.
