I'm trying to adjust the timing on my 67S, but can't get the distributor to budge. I've loosened bolt "A" and and nut "B". It looks like bolt "A" mounts the adjusting bracket to the distributor. Is that right? If that's the case, I shouldn't even need to loosen it, right?
..and what is "C"?
Any idea about how to rotate this stuck puppy?
