To replace the dashpot, best to have distributor out, two screws and fit end into advance plate. It has been 35+ years since I have done that, not sure.
If you count the teeth, the total is 720 degrees at crank. Just checked, 13 teeth, so about 55 degrees, that is a bit much.
I looked at the photo in your link and see what you mean about the bolt underneath,you have to pull the distributor to do that too. If I have to pull the distributor I guess i should try moving the roto counter clockwise a tooth.
