AJ/FormS, That was quite a discussion with lots of excellent information. You definitely had time on your hands to make all those measurements and good skills to know how to chang the springs and such to make the distributor do what you wanted it to do. What spring kit did you use? And what Vacuum Canister? How did you modify the canister?
This post shows the need for someone to make distributor machines available again. Sun? Please come back?
David Vizard has posted a new video, #120, on ignition timing. He prefers manifold vacuum vis ported vacuum in the carb. Not sure this will work well for all street applications, but he has a lot of experience that we can all learn from.
I would love to read comments from FABO experts on both of these discussions. I believe that most people leave a lot of performance and economy on the shelf by not paying attention to ignition timing.
