Thanks jt20,

That gave me just enough play to get the sprocket in and then carefully adjust it to get the chain on the right sprockets. It was hard to pull up and keep enough room in there. I would guess that it would be easier to do with 2 people. I did finally get it on and the cam and crank are aligned at 0 TDC after 5 rotations of the cam so I think I am in good shape as far as cam and crank timing.
