did you put the piston in backwards? i know some one that put one of the pistons in backwards on his banshee. it was hard to fire up and it acted like what you are describing. but his actually started and ran till the piston ring finally caught the port edge and, boom. just an idea. also, my blaster filled up with gas too. i had about 1/2gallon of gas down in it. i took off the reed cage and stood it on its grab bar and let it drain that way. but, it would still turn over like normal when i kicked. it just wouldnt start. now it still wont start but it tries to. this thing is all stock. i rebuilt the carb, put in new reeds, checked all wiring, and disconnected the TORS crap. it still wont start. im still messing with it though in my spare time.
