It ran great all summer, idled perfect, no gas smell in the exhaust. Now it
smells like unburned gas and the idle is occasionally bouncing around and
running high. I thought I had it dialed in pretty good and then as soon as
it started getting cool outside this happens.  Guess I didn't have it as
well tuned as I thought I did.

Anybody else have anything like this going on?  Any insight?
