Your engine is flooded.
Follow Dragon's advice.
Make sure that when you fill your tank, that the fuel doesn't run into the carb or into the muffler.

I've got a new O.S. LA 46. I'm having some problems starting it and as I'm new to the hobbie..I'm not sure how to fix. I prime once. Then I hook up glow heater. Then I attatch starter. It turns for a sec.. then makes a snapping noise. then the whole spinner falls off because the prop nut loosens up..probably because of the snapping noise. Not sure what it is...is the engine tring to start in reverse??? Any help with this would be much appreciated!!!!! The plane is done..from KIT.. can't get the friggin engine to start AHHHHHH.....
