I think I have the differential solved, thanks. But the aroma of gasoline was in the garage the last week, I thought it was fumes from a gas can. I opened the door ran the swamp cooler and it was gone, but returning in a day or three. Tonight while adding brake fluid to the master cylinder I looked at the fuel pump. The pump is about ten years old, the bolts holding the halves together are tight, and the diaphragm is wet. It is time to get an electric pump for this car too. Again I marvel at the thought of a leaky gas pump over the sparking started motor.
