whipper snipper/petrol line trimmer help?
 

i have a whipper snipper/petrol line trimmer connected to my bike. well first of all my dad finished making a frame for it today and i took it for a ride up and down the streets. it ran beautifully for about 2 hours then my brother got home and i wanted to show him. so i tryed to start it and hit the primer a fair few times and it kicked over but not really so i took it round the back and there was alot of fuel leaking from the carberetor where it sucks it air. so whats wrong, did i prime it too much or is the carberetor stuffed? please help
