On the prior adventure, forgot to mention. After I got the car driveable again, I drove around the block. I noticed the (stock) oil pressure gage was sitting about where it sits when the car is hot, even though the oil was certainly close to cold. I checked the oil, and the level was at least half a quart higher than where it was last time I checked. Also, it smelled like gasoline. Could there be a connection between this and the stuck carburetor float? Well, I had to toss 4.5 quarts of expensive Mobil 1. The Texas heat would eventually boil the gas out of the oil, but I had probably 20% gasoline in there! D^2
