When I acquired my BN7 it had been seeing service for some 12 years as a vintage racer. Since it had all the "right stuff" I have decided to restore it rally style. The 3 side draft Weber DC0E45 carbs are part of the package I obviously want to maintain. However I want to be able to drive the machine in daily non-rally fashion. Currently at high revs the engine is raucus and quite potent and at low revs, it is quite docile. However, when accelerating (unless very gradually) through the 2200-2500 RPM range, it has a real "flat spot". I can't use vacuum advance to alter the ignition timing and rejetting the carbs has met with only limited success.
I am considering going to a progressive linkage for the carbs and wonder if anyone in LBCland has any experience in this regard. Usually, as I understand it, such linkages are used to improve fuel consumption, and that would be nice, but I'm really more interested in "civilizing" the powerplant and wondered if this might help.
I also don't know that such a linkage is even available for these carbs.
Any help much appreciated.
