Wanted - 4F8175 Starting Clutch Lever

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
