Wanted - Carb parts for D4 Staring Engine or Full Carb Assy

Hello all,
I went down the path restoring my D4 pony motor carburetor and in the process had to machine a few new parts. One of the parts that seems to be inoperable is the choke plate spring return cartridge P/N 5F7618 in the parts catalog. Does anyone have a spare they're willing to sell? Alternatively, given the number of new parts and repairs I had to make, I was curious if anyone has a complete Carb assembly that would would be willing to sell. PN 5F3527 or equivalent (Zenith downdraft carb used on D2, D4, and likely others).
Thanks,
Mike

I have 5F7618 as the throttle assembly. The choke parts seem to be individual but include the 5F7625 lever assembly and the shutter assembly (the thing with springs on the choke plate that open to provide some relief on full choke when the engine starts. Try zimmerman (Chad Enyeart) he's bound to have a bunch of carbs on the shelf. Or just search for D2 / D4 pony carb on ebay - there's usually one or two floating round on there

I found today 2 shaft with lever and plates with springs and screws and these shaft are 3inchs long for carburator
