Triple Stromberg Linkage
The linkage works out very nicely, using the stock parts and a lever and rod supplied with the kit. Your additional carb will need to be a “rear” carb with the long shaft out the front, and will need one of the long nuts on the rear of the shaft like the one on the front carb. The throttle shafts will almost come together and are joined by the standard folded couplers. This “direct” coupling of carb shafts is a bit more rigid than the stock linkage and does a very good job of keeping the carbs synchronized. I find that connecting the choke cables to two of the three carbs works fine. The stock B1AF needles work very well in the triple carbs.
