47 degrees initial time? help!!!

I would start from SCRATCH

1.....Get a plug piston stop and CHECK it. I made this one in the early SEVENTIES



you don't need a degree wheel, just mark the balancer temporarily each direction it stops, then split the difference. TDC is halfway in between

2....IF YOU have MSD ignition, (or even if not) get an old NON dial back lamp to double check your own lamp

3...Make DAMN sure you are on No1. These ain't Fords..........
