I drove the car back home this afternoon, a 90 mile drive. Not a lot of tools where I had it nor time to use them, otherwise I would have tuned it a bit before I left. It is running very rich, as the blue smoke under hard acceleration has ceased and is now black. I got considerably better fuel mileage on the return trip, using about 1/4 tank of gas.
Lots of traffic in Boone and Wilkesboro, and the cooling fan worked flawlessly.
Has not used any oil since that one time.
