Edelbrock Uni-Syn Multiple Carb Balancing System

 

I've noticed a lot of posts saying it's a great pain to synch in dual Webbers/single Mikunis.

 

Has anybody heard of this tool?  It's used to measure airflow of carbs to synch your 3 Stromberg 94's and such.

 

 

If you have more than one carb on your hot rod, you need one of these "Uni-Syn" carb synchronizing tools. Just set on the top of your carb and adjust until all the carbs in your tri-power three deuce set-up read the same. 

Works well on small one barrel and two barrel carbs (downdraft or side-draft). Fits carb necks from 1-3/8" up to 3".

 

$25 from Speedway Motors.

Cool! I like the idea of a wide band sensor on each exhaust header, tune accordingly.

That would take care of the air fuel ratio (tune).

This tool would be used to get all the air flow the same.

I have never see that one that you have show however, a good syncrometer is a must. I have a STE syncro and it's nice because you can stick it in the carb and its hands free while you tune.

Also eurocarb has a carbtune that has 4 tubes that and you can read all the vacuum at once : http://www.dellorto....artsectionID=17

The throttle linkage screws it up the most, I have a synctec link and do not like it at all. so I'm going to try a weber under mount with two adjustable throttle push rods.

Carbs, I stay away from those things.

Pretty cool..... to use this tool though it has to set vertically? So side draft carbs you would just need and elbow tube of some sorts for this to sit on? Wouldn't mind some day doing a carbed motor. Ironically though in my earlier days of wrenching I was always afraid of fuel injection, but now that I know fuel injection I fear the carb!   I think what it boils down to is trouble shooting which takes tons of knowledge and time but with FI most of the time the ECU tells you whats wrong or at least where to look.

IMO...worthless, never did us any good in the two years we tried to get the hang of it.  We had better luck with a piece of tubing put up to our ear and listening to the draw in each of the intake tracts...

Don't know about this specific balancer, but others that I've seen pivot at the base of the sight glass for use on sidedrafts.
