Hey friends. So I was finally putting in a new set of points for the Distributor I've restored and cleaned up... and while flipping through the FSM pages, I came across the distributor weight governor springs portion- and something is off here. The distributor I have is an Emissions Control spec D612-52 model, as opposed to the D606-52. I believe it is the original one that came on this Jan 1970 car. They differ slightly, the D612- as far as I can tell, has distributor cap clamps that are two piece, and use a small bracket that holds them onto the body of the distributor- one of the small plated brackets has the cap alignment square that makes sure the cap only goes on one way- whereas the later style ones have it cast into the body itself (you could theoretically swap the two bracket positions and install the cap incorrectly on the one I have. Anyways, that's neither here nor there, just a detail on the version I have to avoid confusion or if it relates to the issue I'm having: The governor spring assembly... On the spare distributor from the 71 (later style, cap can go on only one way) that I took apart to look at, the governor springs have two different tensions and are visibly different. This is indicated in the FSM: On the distributor I've rebuilt, the springs are the exact same, and there is no difference between the two, except for #3 and #7 in the diagram- the circular end and the rectangular end. while situated at top dead center (on a bench, mind you)- I put the cam plate in and verified that everything looked like the photo shown, even the small start/end advance angle gap on #2... but the springs are still bothering me. Is this part of the reason why they were "Emissions" style distributors? They didn't advance the gap due to offset weight distribution? Should I be concerned? I am new to points distributors so I am having fun putting it back together, but I'm not sure if it's going to work well. I'm going to try it with the oil ignition coil when I get the car started because I don't want to damage the NOS ignition coil.
