Well, now I'm even more confused. If you look at the pic I've posted you can see I have a 15R and a 21R advance plate. What I don't understand is how the 15R slot is wider
than the 21R slot.
That seams to be backwards according to everything I've read. Shouldn't the 21R slot be wider than the 15R slot??
I'd like to take the whole plate assembly off so I can weld/fill in the slot that is currently being used in order to limit the centrifugal advance. Problem is I can't figure out how to get the advance plate to lift up and off the distributor?? I pulled that foam piece and the clip right underneath it off the shaft but I still can't get it off. What am I missing?
If I do get the advance plate off and fill in the gap, will I have to pull the distributor and rotate 180 degrees if I don't switch to the 15R slot?
Lastly, the limit "pin" seams to have a tiny bit of slop. The pin itself moves just a few degrees. Is that normal or should it be rock solid and not move at all?
Hopefully the pic will show...
