I might call it the CV to VM carb conversion. If you don't know what a VM carb is well lookie here:
You'll notice the throttle cable comes in at the top of the carb and directly lifts the slide instead of depending on vacuum to do the same job. The VM carbs don't have a throttle plate like the CV carbs do, so, they are not the same animal.
Now just adding a different cap on the top of the carb that allows a cable to be attached to it with the cable going down inside the carb to where the slider lives and attaching the cable to the slider itself, wouldn't be too much of a deal to do. But, that alone won't make the carb work right by doing just that. Somehow we would also have to control the throttle plate (butterfly) as well and at the same time as the slider.
So, I got to thinking about how to do that and the idea of a throttle cable, 'splitter' like the one we already have, could be used to pull the throttle plate and the slider at the same time. Obviously, this would require two splitters, one for each carb going to the existing throttle splitter and that makes for a lot of splitters, so off I went digging on the net and found a four way splitter that could do the job of the three it would otherwise take to make it work.
Right now, it's just an idea and there's more research I'd have to do on the carbs to figure out a good clean way to keep the vacuum from affecting the slider, which might be as simple as plugging the hole that goes through the slider, which could be easily done by tapping the hole on the top end of the slider and inserting a screw to plug the hole.
Now, if I can figure out a way to incorporate this idea along with another I have, which is to get rid of the idle sync cable, that would be something!
