Small update: I believe it to be carburetion. I have a steady 7V at the coil with a battery charger on it. That doesn't change, so in theory, the spark should remain consistent, excepting condencer and coil. Coil is new, and dist components have no miles on them. So I get a little gas dripping out of the bottom of the updraft carb drain hole when it cranks. The pump moves freely, but the sleeve seems to be stuck and I can't get the pump assembly back out. float level is OK.
