Hi Steph, I’ve only just caught up with the Scott site and was interested in your problems. I have a ’47 F/S and run the timing on 32deg.BTDC on full advance.
I can’t remember the figures now but knowing the flywheel diameter you can work out what distance 32deg is and having found TDC make a mark on the flywheel with reference to a datum on the crankcase and measure back the distance you have calculated and put a mark on the flywheel, then time to this mark.
The other point is that although you can adjust the timing on the advance/retard lever this is only a temporary measure and the mag will have to be retimed as the internal timing of the mag is set for full advance.
My bike runs very well and the timing seems spot on. Hope this is helpful
