IDF mods. Weber gods please help!

I'm a dellorto guy.... So sorry for the dumbarse weber question...

Fitting some 36idf webers to a mates car... Done all the usual stuff to make them work, but one thing that I have not been able to confirm, is what to do with these little ports on the sides of the carbs....



What it looks like when pulled is this....



I believe these to be vacuum ports for the ignition...

So the simple question is.... Do I pull them out and find a suitable plug to replace them?

Cheers.

Just leave them

I will try and find the Harney Carburettor Clinic article

Sorry - Harney, not Haynes

Here are photo of mine, hope this helps.
