I just wanted to show my linkage for dual W-1 carbs. This was much easier to keep both carbs in sync and to connect the throttle. carb connection , complete view. I just braised a nut for a spacer and a collar with a set screw to each carb, one side to the throttle arm and one side to the accelerator connection plate. Once I had the carbs in sync I was able to just tighten the set screw and they were set. This was really easy to make for a good direct linkage. The brass rod is 1/4". I may have to go to 3/8" as I am not sure how long the small set screw will hold on the 1/4" collar. A 3/8" collar would have a larger set screw and work better, I think.

If you never tell a lie, you never need to remember what you said.
