Customers find this product to be of high quality and easy to use. It's particularly valuable for synchronizing carburetors on vintage cars, multi-carb setups, and progressive setups.

I use this tool to synchronize carburetors in old British Sports cars and in my old Mercury Flathead tri-power hot rod. It is simple and accurate.

I didn't get a chance to use this. I bought 9super7's. The secondary carbs don't have fuel air mixture settings and I'm running a progressive setup.

This is the simplest way to really get the synchronization correct, be it a Corvair or a Jaguar.
