Identify this part off my carb?

[Hudson.]

Hi guys,

Dissasembling the PD46A carbs off my 550K3 and this plastic shim fell out from somewhere. Im not sure how it was fitted or where it came from exactly, can someone help?



Thanks in advance, apologies for the silly question!

I think(therefore I am) its somewhere in th complicated choke linkage in the middle

Thanks Bryan, im 90% sure its a plastic shim that fits onto the slider mechanism on carb *2. As theres no sync adjustment on this carb, the linkage which mounts to the throttle spindle is thinner and requires this shim (it fits perfectly, but might just be a big coincidence!)
