I have a photo of my adaptation for my carburetor set up.
I have a conventional throttle rod from the steering column to the bell crank on the manifold and a modified Model A throttle rod from the bell crack to the carburetor.
That is a nice and clean set up. Well done.
How does it run?
Neat! By the way, that is a Model B type carb. The B's used a cable connector to the GVA (gas valve adjuster) that you could pull for choke or twist to adjust the fuel. If there is room the Model A style rod assembley will work.
The engine runs good. I replaced the worn throttle shaft with a part from Snyder's.
I use a modified choke rod from a Model A. It goes through a floorboard and works as intended.
Yes I know you know it's a Model B carb, I miss read into what was written. AM needed more coffee!
A few shots of my installation a few years ago-"B Manifolds and Zenith II carb" on my '12 Touring. All works very well,producing additional power when needed. Enjoy; Tom
