Well here is the deal. Start it up kinda runs rough. Slowly rev it up it will rap all the way to 6000 fine. stomp on it it will die. put it in drive and take off slow it will do fine. stomp on it it will die. after it dies it is hard to. will try to start and stuble really bad like it is running off 3 cylenders. wait a few try it after a bit if cranking it will start?? any idea's????

 

hmmmmm what can it be.
