How and what does a syncrometer do?
As the title states, what exactly does it do. I understand its part of tuning carbs/ITB's. I also understand that it basically give out a reading of how much vacumm is being pulled through the opening of the Carbs/ITBs. But what do you do with that reading? How would you change things from one opening to the other? I'm just curious if it would really help in tuning and what not. Thanks

It shows you how much air is entering the carb. You need to tune each barrel until they're the same. If it happens to run worse once you do this, fine tune one or the other until it's smooth.
As for measuring vacuum, I don't know about that. It just sits on top of the air horn thing and shows you on a guage how much air is flowing.
That's all I know about them. I could be mistaken. A local Weber expert used one on the black '83 with the 48 IDF and the above was my personal observation of the tuning process.

does it actually calculate how much CFM flow through it? I thought it would be like a big vaccum meter. Also what exactly do you adjust to alter the flow of each single carb? The butterflies can't be changed positions (unless you "twist" the rod that holds them"

well I was considering htis for my ITB setup, for fully tuning it. Not sure how the A/F ratio would make a notable change in flow though. When you took your car in to get tuned Jeff, what was the outcome of it before and after the syncrometer adjustments. I'm sure he probably did more things too it but curious on what kind of real HP output it would of given you. I would image a smoother idle, and smoother all around engine would do something too.
