Choke Plungers Failing ?

Thanks for the reply Zed even though it wasnt what I was hoping to hear.
Lots more work than I had hoped plus cost of new airbox rubbers as the current ones are pretty solid and struggled to fit them back on again a few years back.
Is there any other rubber seal on the choke plunger assys apart from on the tip (o ring inside the recess etc) ? 
Also is there a rubber boot that sits over the top?

Apologies for keep picking your brains Zed but once the carbs are taken off the rack does that involve extra setting up or do they locate back precisely.
Ive only ever stripped and cleaned them still on the rack as somewhere in the back of my head I seem to remember seeing somewhere that once taken off the rack it involves a lot of extra setting up over and above normal syncing.

There is an 'O' ring that sits under the nut and a dust cap that goes on top.

I'm cleaning/rebuilding a set of early vm 28sc carbs (early 1974) when I dismantled these I found no sign of these not even any small bits. In the diagram I'll post below part #15 choke plunger O-ring, There is an asterisk next to the part # that states (These parts may not be required) so I take it that these early carbs don't require these O-rings ?

Thank you very much for the quick reply zed! One more question if you don't mind.

I am missing three of the felt dust seals part #11 would it be ok to run without these ? If not where would I find them.

And Thanks again you've been very helpful !
