Review on 🔧 WINMAX TOOLS AUTOMOTIVE Carburetor Synchronizer & Adjustment Tool Kit – Vacuum Gauge Set for Gs Kz 550 650 750 by Mohmed Burt

4 sensors to test; if all are connected to the same vacuum source, e.g. B. a main carburetor or a manual mityvac. On the Mityvac I sucked on 5 and 10 inches of mercury and compared all 4 gauges. My results were as follows: 3 gauges had the same reading and one was at 2 inches Hg. Fittings and 3 other vacuum hoses. And at the needle stabilization knob, he controlled the rebound of the needle. This tool is a guardian for me.
