I'm running a bprojetcs manifold so the mounts for the throttle shaft are built in, so I can't use the independent ones you have shown up there ^ The issue I have is the arms that connect the throttle lever (sitting on the shared throttle shaft) to the individual carb throttle shaft itself. It has the two little sockets each end and a couple of adjuster nuts on it. Yeah, well one of those is a little sloppy so it's a little difficult to tune around. Tomorrow I'm going to try and reduce the pilot jets to see if they affect the early acceleration, if they don't I'm banking on it being the carbs out of synch and the pilot screws not quite as good as they should be. Fingers crossed.
