Well, it's my turn to ask for suggestions..

I would just like to mention, one trick I used a long time ago to find the right keyway position on a multi keyway timing set was to use a factory timing set at dot-to-dot, then slide the stock chain and gears off, and lining up the keyway in the multiset to determine where "straight up" was intended to be on the multi keyway deal. Of course the correct way is to degree it in, but I was doing it in the driveway and I didn't know any better at the time, lol.
