I read an article that mentioned tapping a hose line connector to each intake manifold and running a rubber hose between to equalize the pressure.
Has anyone done this?

my dual solex 34 kit came with the tapped manifolds, fittings and hose to do this.... i had a single stock solex on it before so i dont know what would happen if you didnt have it.... but it runs and great, throttle resonse is SO much better with dual carbs than the single.
A balance tube between works well when you have two single throat carburetors each feeding a pair of cylinders.
George,
Would this not be recommended for two twin throat carbs feeding a pair of cylinders?
Thanks

I have the balance tube as well and I have to pinch it off when it comes time to sink the carbs.
Balance tubes are not necessary with dual twin-throat carbs; in fact they should be avoided with this configuration.
George,
You say avoided. I'll need to "power" my brake booster from my new IDF 44s.
Today its hooked up to my kadron balance pipe. Is it not advisable to hook it up to multiple manifolds when I make the switch?

simon, vacuum is vacuum, once it draws against your booster it goes
no further. i don't see any benefit from multiple pick up points.
besides it would lessen your "dual" carb benefits.

I think the problem with running a balance pipe on Webers vs Kads is that the Webers are effectivly 4, 1 bbl carbs - one feeding each cyl. The Kads are 1 bbl carbs so you have 1 carb feeding two cyls. The balance tube connects before the intake manifold effectively splits to the dual port heads. This provides some communication between the carbs and can help compensate for minor out of sync conditions. To have a balance tube on the Webers you would have to fabricate a 'Y' pipe on each manifold and connect a balance tube between the two 'Y's. If you hook the booster to one carb intake runner on a Weber, all will be fine as long as the booster is at "full vacuum". When you brake some vacuum will be lost through the booster operation and the cylinder whose intake is responsible for the vac regeneration will run like crap until full vac is restored. Or at least that's how I think I see it. Could be a real problem.
