Ran it today just a bit. Still some problems so did the valves one more time. Now appears I'm getting dirt and debris in the needle assembly as a by product of replacing everything from the tank to the carb inlet. I pull the needle, clean it out with compressed air, reinstall, and set float level. Take it out for a short test run, and start getting a little smoke from driver side pipes and what sounds like a miss fire. Get back, and the float bowl is flooding again. So back to pulling the needle and cleaning it. I am now working on the assumption that the needle is getting stuck open while I'm driving and that's dumping fuel which is fouling the plugs and running very rich thus creating smoke and mis-fire. Is this a logical assumption or should I be looking at something else?

Also, need to run it long enough to get the lifters really pumped up and then set the lash. Sometimes it sounds like my old solid lifter cam when the lash was off - wild sewing machines under my valve covers!
