Andrew, Rice Equipment in PA. would have a new cap. At the back end of the mag under the tin cover there are 2 little screws in a plate with many hole. you unscrew the screws and move the plate to change the timming and put the screws back. Move only one hole than test run it. You should hear the mag snap when piston is at TDC.
If you remove # 1 plug put a screw drive in the plug hole and crank slow as piston comes up. oldiron29

Quoting Removed, click Modern View to see

be sure to hold onto the mag end of that coupler because if it has stopped at a spot where the impulse sprig has started to get wound up it'll spin backwards and you could lose track of which hole the two little bolts were in

Turn the engine until it snaps. I would mark it too to see how much you change it.
