Thanks for your reply, Don. You got me to thinking. Hesitation can be an electrical thing, too. As I recall, insufficient spark advance can be the culprit. Now, if I can get my mechanic to dig out his timing light... I'm old school, doing it by ear. Your rough idle may have been the result of too much advance.

So often, we get fixated on one or the other: spark or gas. The same symptoms can often be caused by problems in either one, or both.

I'm going to set the idle jets between the specs at 1-1/4 turn. (Specs say 1 to 1-1/2.) If that doesn't work, I'm check the timing. If that doesn't work, go after the carb again.

NOTE: The thing starts like it has electronic ignition, so I hope it's not an electrical thing. It acts exactly like the hesitation you get with an old EGR valve equipped car when the exhaust gas valve opened too fast.

Anyone know how to test a Temp sending unit without taking it off? It looks pretty gnarly.

I'm going to wiggle some more wires under the instrument panel, too, especially the voltage regulator for the Temp and Fuel gauges. Both of them being out at the same time and wired on the same circuit is mighty suspicious.
