Here's a pic of the shortened arm and pivot, with bronze bushing and screw collar.
I was able to make a new arm for the choke coil and connect it to the same arm as the front carb.
The long rod to the carb was set up to have the same angle as if the choke coil was installed in a stock configuration, but the rod from the choke coil ended up being a bit lower than it should be. The setup can get stuck and flip around to the top side of the slot in the coil. A slightly longer rod would keep this from happening so I may do that next time.
The whole setup:
And it works. The only issue is how to secure the 3 rods to the arms on the torque shaft. The bar I used is too thick for the standard choke rod clips- those one with two little clips and two holes to capture the rod and attachment point. Since I changed the side the rod attaches from at the carb to avoid interference issues, those clips don't work there either.
So I used some brass wire to hold it all together. That worked fine, but eventually it bent a bit and came loose, or bound up and the whole setup stopped working. I'm most of the way there, and it was a good project.
