Hi there,

Looking for a cheap(ish) carb balancer suitable for 40 DCOEs if anyone has got one they want to move on. Trying to sort the on-going saga of my poorly running crossflow so now trying to verify the carbs are balanced.

PM me with details if you have one for sale.

Many thanks

Andrew

Hardly worth trusting a second hand one is it, they are dirt cheap new now

Looks great thanks. Being able To see 4 at once would be helpful - apologies for the stupid question - will these work with DCOEs? I had always envisaged something that measured from trumpet part.

If you think these will do the job on DCOEs I’ll get a set.

Thanks. Andrew.

Not selling, but I have a Morgan carbtune. See all 4 really helps as you can see how adjusting one affects the others.
Some carbs ( dellorto, bike stuff etc,) tends to have a vacuum take off which is ideal. Otherwise drill/tap the manifold to M5 or 6 and use MIG tips as take offs, bolt after to plug.

If you want a single type, plenty of those about, even gunson. But the very best are the old Crypton Synchro Check.

I may have a Gibsons one kicking around the garage, will check later

Gunsons, not Gibson (flippin autocorrect)

I set the fireblade carbs up on the pinto with a differential manometer made from 6mm polyurethane air hose and a couple of t pieces.

The mainfold vacuum is greater than 7 feet of water at idle (height of garage ceiling) and with a simple manometer to atmosphere, it was slurping all the water out, so I set up a manometer with ends connected between 1 and 2, another between 3 and 4 so any pulsing would be out of phase to stop any resonance, then ran another manometer between 2 and 3 to balance the pairs relative to each other. The whole setup is now balanced within about 1/2" of water overall, far better accuracy than the part to part variation of the calibration of cheap vacuum gauges and better resolution to boot.

I cobbled it together with stuff I had in the garage, but buying the tube and a pair of t pieces, I can't imagine you'd be looking at more than a tenner. It's cable clipped to a piece of 3x2 that sits with the wood store in the corner.
