Inconsistent idling problem

The update on the carb was that it seems to be running more consistent in regards to the idiling after some changes to the idle mixture, and some more time spent working with the fast idle cam adjustment. For right now it seems like the temperature of the engine is making the idle speeds fluctuate 100 or so rpms during curb idle operation. I have not experienced that with my previous carberated cars, but it sounds like it is pretty normal.

Trailbeast; you were right on the money with the area to look for the gas leak. The grommet was fine, but the vent tube had a small hole in it. I replaced that, and the smell is completely gone. Thanks for the heads-up on that.
