Final Update
I'm in tall cotton! Left the truck for a couple weeks, came back, gave it two pumps with the accelerator, pulled out the choke, vroom vroom! Analyzer says I have dwell at 30, rpms at 500. Vacuum gage is holding fairly steady at 20 measured under the carb.
Thanks to you all for the help in getting through this. If anyone else is reading, my recommendation would be to start with the carb rebuild, and then work from there.
Mucho appreciado.
Bill
