Hey i put my 38pwk on today i didnt put my clamp on tight by the reeds and it was zingy and wouldnt rev out Just wanted to die.If you have the that bad boot still that could be it.Mine wasnt ripped or anything like that just wasnt tight and it leak bad and screwed up it bad.If you do get it running you will burn the motor upo from the leak.Also when you gassed it up after riding it are you sure it was good gas.
