I lined the cam tower marks up, and the dial on the crank was showing about 18 degrees out. I did a little marking test, and it appears to be equivalent to one tooth on the cam sprocket. Based on the fact that one of the previous owners likely replaced the timing chain, it seems likely that they jumped a tooth during the installation.

If I am able to lock down my split timing chain, am I able to just move the cam sprocket one tooth back, realigning the cam marks with TDC?? My other concern would be that the fuel pump timing could likely be off if I am able to successfully move the cam sprocket without chain movement. How would I be able to re-time the fuel pump??

Thanks for the help!
