Carburetor Vacuum Synchronizer Gauges Tool Kit

Motorcycle Four Cylinder Balancer Vacuum Suction Meter Fuel Vacuum Carburetor
Description
It is used to test the pressure of the fuel pump carburetor and whether the engine with 2-4 carburetors is synchronized and balanced during operation. Each 2" gauge features 0-76cm/hg readings, and shut off valve and all hardware is brass finished for longer life, higher corrosion resistance, and better flow accuracy. Airflow control is handled by needle and seat valves instead of knobs. This helps to resist the dial indicator "bounce" associated with many other lower-quality gauges. The set comes complete with a red mold storage case. This kit lets you synchronize the values of the 4 carburetors as well as adjust/set them.
