    If it runs without the lean spit when you pull the bottom plug wire, then it would seem to me that the problem is most likely with the lower crank seal, if there even IS one, or some other air leak having to do with the lower cylinder.

    Or maybe the synch and link is a little off and the throttle valve is opening a tad early?

    Long live American manufacturing!
