Ha!! Agreed on the rope. I took these pics today to show the timing marks. I put some white stuff on the crank gear to show where the tining mark is but the mark shows up well. You see the O on the cam gear. These two marks don't match up exactly but as close as I can get them. You can see the cam gear marks on a tooth and the crank gear marks on a tooth. These marks can never match exactly. Is it possible I have the wrong crank gear? that's the one I replaced.
