As the Boyer is the same arrangement as the Pazon, The Boyer I suppose would also full advance at 1,500 rpm which is kind of what I see in the timing light beam, a slight flicker towards TDC when I allow the revs to drop but holding steady at my .2 mark with 2,000 plus rpm on the tahco. I will wait to see if a top end speed is posted to try and make more sense.

The bob weights you have are the earlier type. I have some but do not sell them just in case they fail as I obviously don't want to be responsible for damaging some ones ignition system. I think they fail for one or two reasons. First heavy handedness and secondly poor casting with weak spots caused by slag.

Not that many have detached themselves but a few did go all around the same time. This was a few years after production stopped so I don't think it is a given they will break.
The other type with the bronze bob weight, I think was done as an easier and cheaper way to make the advance and retard assembly.  Thanks for your reply.
