Steve,

You hit it on the head. My original post spoke of the idle being off - it sure seemed that way. It appears that it was the dampener screw. It was adjusted almost all the way out. When I tightend it to most of the way in, the problem vanished. After two days of fairly cold starts (no problem), and a couple of smooth trips around town; I am ready to declare success!

Thank you,

Dale Mitchell
