One that I do not wish to repeat, Al. 
The test drive of some 20-30 miles went well. The throttle seems a bit sticky, with a hot idle of around 1300. I've chased this off and on several times and won't let it stop me from driving. Something is binding on the throttle linkage.
More worrisome was one of my stalling incidents that plagued me on the last Carlisle trip (2016). I had thought that I traced it to overfilling the gas talk and getting fuel in the vent hose, causing some kind of a vacuum to be created. It almost always occurred within an hour or two of filling the tank on the road. This time it happened with less than half a tank, but still was resolved by popping the gas cap off. I don't want to be stopping every few miles to do that, but it could be months before it happens again. It's just seems random except that it almost always occurs when I'm running at highway speeds. I've swapped fuel pumps, so I am pretty sure that isn't it. At this point I will probably drive the Speedster, but if anyone has an idea what this might be, I am all ears.
