Any farther out and it starts spitting fuel from the carb... a definite sign of flooding or positive pressure..

This, to me sounds like the engine is flooded, it runs until it leans out from running backwards, then it gets so lean that it backfires, kicking the prop off.
dmac, try this... Put your finger over the carb intake and turn the prop counter clockwise (looking from the front). Do you feel your finger being sucked into the carb, or do you feel pressure?
If you feel pressure, somethings not right, stop there and let us know. If you feel suction, close the needle valve all the way, then pour a few drops of fuel into the carb and try cranking it up. if all is well, it should start for a few seconds until it burns off the fuel you primed it with. Then crack the needle valve open a bit and repete the process until it keeps running.
