Review on 2-Channel Digi Sync: Advanced Digital Throttle Body and Carb Sync Tool - Model DS3 by Tony Dago

I bought a 6 channel digital sync to keep my carbs in sync after a rebuild. The carburetors were dubbed on the workbench, so in theory they should have been pretty expensive. As soon as I hooked up Digital Sync I saw how far my readings were and I was surprised. When I adjusted the values to the main carburetor I saw that my RPMs dropped as the engine ran much better. The great thing about this product is that it displays RPM, which is very handy if you only have a speedometer. This will help you set the correct idle speed. I have used dial gauges in the past and this product is much easier to use.
