I didn't like the idea of a cable so I fabricated linkage based on the same principle as the 1 bbl linkage. I even used as much of the 1 bbl linkage as possible. It works the exact same, the only difference is the push-pull is horizontal instead of vertical.
carb linkage 1 carb linkage 2 The arm you see that's attached to the painted blue shaft is the same arm from the 1 bbl and working in the same capacity. Solid, mechanical linkage. No throttle response issues.
