I think fast64ranchero has my mistake pinpointed, I now need to find a new pin and the spacer he is talking about, I think I have misplaced it somewhere---this is what I get for working on the overhaul over about 6 months time, I thought the new cam might have had a pin in it and the old cam would still have a pin in it---nope----I had to switch the pin into the new cam evidently as it is not in the old cam.---what I have sticking out is the oval plate that is covering the front of the cam and it sticks through that, then the pin in the hole in the end of the cam, then I had the sprocket on to the pin, then a bolt in the end of the cam with a washer on the bolt that holds the sprocket on along with the bolt when tightened, I must be missing the spacer he talks about that goes between cam sticking out and the pin----confused yet--I am ---
