Well, finally got all my receipts and notes in one place and here are a few interesting facts about our trip. We were 30 days on the road, drove through 16 states and put 6926 miles on the little black coupe. We had 90 meals out and lots of ice cream stops. Mechanically, had to deal with a broken alternator bracket (replaced with baling wire), and pulled the carburetor off and either changed it or took it apart and re-assembled it at least 5 times. We did have vapor lock issues until I wrapped everything up in aluminum foil. I only lost two parts, an air cleaner in Michigan (forgot to safety it on with baling wire) and a turn signal flasher somewhere in Arizona (more baling wire holding the new one on). The moral of that story is: carry baling wire and use it.
Put a set of new Firestones on before the trip and I must say they don’t show any appreciable wear, I think they are using a better rubber compound now. We filled the gas tank 52 times, and changed the oil twice. We had an increasing oil leak as the trip went on, don’t know why yet, that will await a little disassembly of the engine. Anyway, we added a total of about 17 quarts for the total trip, mostly on the way back from Michigan. The Tillotson carb (when it wasn’t leaking) performed the best and got 17 mpg going and 18 mpg coming home. The Zenith, which was on for about 1000 miles, mostly in Michigan, got a tad under 17 mpg. Overall, we did 17.2 mpg from start to finish.
