How many carburetors can be synchronized at one time?

The two-gauge synchronizer connects to two carburetors at a time so their intake vacuum can be balanced.

What is included with the carburetor synchronizer?

It includes two gauges, mounting bracket, hoses, dampening valves, instructions, 180mm extensions and 65mm extensions with 5mm threads.

What do the dampening valves do?

They steady vacuum pulses so the gauge needles can be read more accurately.
