Series 3 Identifying carburettor linkage function

hjdowning · Nov 16, 2018

I have a Zenith 36 VI carburettor.
There is a mysterious unconnected linkage arm (sorry, I don't know what it is supposed to be called)
Can any one help me identify it/ suggest what it should be connected to (if anything) ?
Below is a link to a photo, part in question highlighted in red, sorry for the bad quality/angle.

Many thanks
Henry.

Not had a petrol landy for some time but I recon that may be the accelerator pump linkage.

That's a mystery, there isn't anything like it on the carb I have squirrelled away and it isn't shown on the pictures in the links that Blackburn has provided.

Maybe, but isn't this the accelerator pump linkage?:

Thank you, I'm going to assume its on there mistakenly, maybe a carb transferred from a different vehicle?

I guess it will remain a mystery

sometimes reaplcments come with arms for both rod and cable or left of right rod connections so there's often a spare. Another option is that some carbs can link a fast idle to the choke but it not always used.

The round section rod to the right of our mystery linkage is the fast idle for the choke.
