Carb synchronizer Pro-Sync synchrometer "SK"

Weber Carburetor Syncrometer SK Type 1-30 kg/h
Designed for Synchronization of Dual Carbs. Universal for any dual carb setup.

Snail Type Syncrometer Carb Sync Tool, BK is the best carburetor syncronizing tool made to syncronize the Weber 48 IDA or EMPI 48 and 51 EPC carburetors. Rather than measuring manifold vacuum via a restriction, it sensitively and accurately measures airflow WITHOUT RESTRICTION. This is the top quality BK Gauge.

This fits inside the barrel (mouth) of the carburetor, fitting airhorns from 2" (51mm) to 2 5/8" (67mm) in diameter. It requires an adapter to use on the smaller Weber IDF and Dellorto DRLA carburetors.
