Question air leak?

If you are confident that you've got the carb in good shape (which would obviously be the first culprit) I would suggest an air leak, maybe where the carb goes in the manifold. I have the Indigo PCV kit (which adds a spacer & second carb gasket to the mix), and I noticed that I didn't get all the gasket material off one surface when I took mine home over the winter..it is a little hard to see the flange on the manifold since it hangs upside down. One check is to spray some starting fluid (ether?) or carb cleaner around the flange(s) to see if it sucks in any fluid thru a leak and changes the engine speed.

Be careful spraying that stuff around a hot motor..I don't think it would be a real issue, but you don't want any spontaneous combustion if it hit a red hot part

edit - FR's got a great idea too..double check using the Moyer Manual that your settings are correct.
