Picture is of my HEI distributor, with the cap off.
Dumb question - how do I get to the centrifugal advance springs? Do I just remove the two screws on the rotor? Couldn't find this info anywhere. I would like to dig into this (timing) and check things out. There is a good bit of info here on the topic so I thought I'd check it out. But at this point I just want to get to them.
