Hi David,
A friend of mine has a Uni-Syn that I use. He has a "single" one not =
the fancy "multi" kind. It works really good but I'm too cheap to buy =
one. Basically, it measures the amount of air going into the carb. When =
you syncronize your carbs all you are doing is trying to get equal air =
flow into each carb. So with the air cleaners off and engine running, =
you place the Uni-Syn tool over the mouth of one carb. A ball rises =
inside a tube showing the amount of air flow into the carb. You repeat =
this on the other carb, adusting the idle screw to get the little ball =
in the same place in the tube. Make sure to loosen the clamp that =
connects the thottle shafts between carbs so the idle can be set =
independently on each carb. It takes the place of listening thru the =
tube and is more accurate. You still have to set your mixture. It only =
helps you syncronize the air flow thru the carbs.

Scott et al.:
I learned to tune SUs many years ago with the hose in the ear method and =
it
seems to work fine for me. There is a knack to it, but with some relaxed
practice I believe most can learn to do it.
My No. 1 son has a Colortune rig and tunes his 1600 coupe =
satisfactorily. I
am R/G color blind though, and try as I might, I absolutely cannot
differentiate the colors he shows me when he adjusts his carbs.
Has anyone used the Uni-Syn tool? It looks like a neat gadget to me.
