Timing chain misalignment

This is a Rollmaster set. I bought, and paid for, a JP set but was sent Rollmaster. Doesn't matter since they are basically the same.

The gear is not backwards - the timing marks are on the front where they should be. It's something to do with the machining of the two gears. I will have my machinist take some off the back of the crank gear, and will likely have to use shim spacers between the nose of the cam and the cam gear.

And I too prefer double-roller for longevity, and the multiple keyways is a much cleaner way to vary timing than the hole and offset bushing.
