Is it possible to fit an overflow pipe to an AUD146 HS2. If so how, please?

You’ll need a different lid with an overflow port / breather vent

Eg

https://www.barnfindspareparts.com.au/s ... id-aud9210

This is the standard type with the pin hole

Quick question: On the Barnfind lid, (AUD9210) is the 2nd brass vent for supplying the other carburettor in a twin set-up rather than an overflow?

I couldn’t tell from the photo Bill. There seem to be many different versions, some with the second port at 90 degrees to the inlet, some at 180 degrees and the same applies to the overflow port.

Some have an inlet, second carb port and also the vent

Generally the 9210 secondary pipe was an overflow - application to MGB etc

My AUD146's have the small vent under the metal clip. Can this be drilled out and a small pipe fitted?

It’s probably possible, but it’d get very close to the fuel inlet rubber hose.
