I have a set of old-style Dellorto 29s for the Ambo I'm restoring.

I found that the "standard" flipper chokes do not fit because the bosses
on them are different from the cable-type chokes. So I cut down the
bosses on the flipper chokes (these had an o-ring) with a Dremel tool,
but I'm sure these modified assemblies aren't anything near air tight.

But do they need to be air tight? There's a rubber seal at the bottom
of the cylinder (for both style chokes) that must close off the orifice
to the carb, so what purpose does the o-ring on the boss serve (also,
the cable-style boss did not have an o-ring).

Anyone dealt with this?
