    Sounds like your chain is too loose. Tension it with the chain tensioner, but not too much. Make sure it has about an inch of deflection from normal.

    oops forgot to put the spark plug back in thanks runs fine with the chain tensioned must of stretched or the tensioner shifted positions

    Yep the standard chain tensioner can come loose and shift on you depending on its design.
