I fixed it!! I found 2 specs for the coil to flywheel gap, .006-.010, & .010-.014. At first I had set the gap to .010, right in the middle, right? No spark, later, after R&R the coil several times, I had set it to .008. Left it for a couple of days, today I tried a different sparkplug, still nothing, R&R the coil again, and set the gap to .012. I now have spark. It runs!! Sort of. The carb is badly corroded inside. New carb on order.
Thanks everyone for the help.
