viking, thank you for that site. I read over that while I was rebuilding it and got everything within spec, but that's a good reference site.

dotgone, I didn't know about the thin layer of oil in the accelerator pump as the directions I got didn't really mention anything. It was just an exploded view that you had to reference to get the thing back together, no written directions.

Pump discharge ball - if you're talking about the little ball valve, yes I got that. It didn't have a weight associated with it (maybe I'll recheck that), but it did have a pin that held it down.

Thanks guys, I'm pretty new at this stuff, so bear with me while I learn

Oh yes it ran fine before (except didn't respond well to throttle mashing and some gaskets were shot) and I can't figure out what changed between then and now. I'll just have to play with it some more. I hope it's as simple as accelerator pump plunger getting stuck.
