Hi Nolan, take the air cleaner off and spray in through the carby, not a lot, just a whif and see if it starts straight up. Carby air leak maybe around where the carb connects to the barrel, probably unlikely but is possible. This won't cause the carb to flood but it reduces the suction through the carb on start up. Then there could also be some issue with the carb internally, not sure what the situation is there.
