oil puke.. no I didn't drink it

As mentioned, boost the timing, there are several threads on how to establish "initial timing" and then limiting total timing. That will allow you to close the throttle at idle, and prevent run-on. Your idle mixture screws might become more effective as well.

I'd take the 2 vent hoses off and plug them, take the oil filler cap off, start it up, and put your hand over the oil filler to feel how much pressure (blow-by) you have, rev it up a few times,, the pressure you feel is likely what blew the oil/dip-stick out.

I hope I'm wrong, regardless - hope it helps
