You would Tee it to your fuel line, and then to each Carb on the Manifold/ or throat vacuum fitting. It is a hand pump basically for squirting a small shot of fuel into the motor, just like an accelerator pump would. Where to mount it? Well maybe a bracket back down under the carb rack?

I don't think we'd need the primer, but thanks for the suggestion. The problem is the bikes like to run with some choke even after starting until it gets warmed up for a few minutes. So we'd still need the sliding plate. If it can seal off all the way, that should be enough to start fine.
Let me see if I can find a good pic.

I still think the easiest way to fix the flaps is by filling the hole with epoxy and like apbling says you just adjust you choke lever position to approx 70-80 closed.

Maybe for a very limited run, carve them out of billet on a CNC. Anyone know if CNC can do something this small?
EDIT: I just noticed the pin is walking out on the flap in the photos above. You can see it poking out on the right. That carb is not in use yet, though. I'd need to re-peen that before using.
This one below is pressed in correctly.

The epoxy gives me a piece of mind knowing my machinist skills won't be whats between me and having someting come loose and cause more damage.
BTW, I don't think the bodies are actually aluminum, are they? I thought they were some sort of zinc alloy... at least they don't seem to be aluminum.

The bodies, I assume are basically pot metal. I think that is some sort of aluminum/zinc/ alloy... maybe some tin? Don't really know.
I did noice a little white crust where brass meets body on some older sets that sat for years.
Maybe brass would be ok though. I think it would be stronger than aluminum shim and probably less brittle than stainless shim.
Remember, I'm talking about the entire choke plate, not just the flap. In order to be able to install the plate and control the plate there would have to be some sort of flexible link to attach to the control arm.
Just thinking out loud I guess...

It would seem the best way to go about it would be to somehow stamp them out like the original, but then they would still be thin like the oem ones....I dont think it would be that difficult to cnc a solid one, maybe when i take the carbs apart ill investigate making an autocad file of the choke plate, but no promises, i really only use autocad for architectural work.

Since i am a machinist i can draw one up in SoliWorks and machine one out sometime. I am very busy right now so it will have to wait a little while.
No hurry. (At least not for me ).
I just don't know if molding solid plates would be easier than machining solid plates out of billet, or not.
Glad it's running better Apbling.
