My car runs much better now after freeing up my distributor mechanical advance. Based on how well it revs and runs now I’d say it’s been stuck for as long as I’ve owned the car (10+years). I also did the Crespin 5 minute strangleberg mod. It does seem to have a slight hesitation if I quickly floorboard the car that it didn’t have before. However, it didn’t rev that quick before so maybe it prevented any hesitation. Also, my 70 model has the non-adjustable needle jet strombergs and the the undesirable vacuum retard distributor so that may be part of the issue. I just bought the adjustment tool from Moss before realizing mine aren’t adjustable.
I simply removed the pushnut washer from the dogbone link on the carb side, unhooked the dogbone from the carb then moved the spring from the hole in the secondary lever which is in the 3 o’clock position which pulls clockwise shut to the shaft just behind the pushnut washer (9 o’clock position) on the engine side of the dogbone link which pulls counterclockwise open. The rear carb was the opposite. I moved the spring from 9 o’clock to 3 o’clock. The pushnut washer on this end keeps the spring from sliding off the shaft. On the front carb I was able to leave the dogbone in place but unattached on the engine side.
The rear carb required removing the dogbone connector due to slight interference.
