Lynx II, hull # 4225

[Lynn Eades]

Dave, there appears to be two key ways in the Lynx pulley? One is notched deeper than the other? Did you have it fitted with the deep notch to the timing gear key? The only thing there is the timing gear which probably lined up fine with the cam gear, otherwise you'd have noticed. So, does the Lynx gear have a rebate in it to allow the longer notched end of the pulley to go further in?
Unless there is a difference in the crank, which I doubt, then it has to be right there. You dont have any spacers other than the slinger?(which fits over the key)
You might have to remove the timing cover to compare old and new?
Good luck!
