• For synchronous measurement on 2 4 carburettors with vacuum connection to the carburettor
• After adjustment and inspection of the valve clearances the carburettors should be synchronised
• Universal usage
• Unit for vacuum measurement: 0-70 cmHg / in0-30 inHg
• Generally necessary after a major inspection
• Optimum results for mechanical function-free engines
• Must be used with running engine
• Pressure gauges are fitted on the plate
• In durable plastic storage case

Application range: Multi-cylinder engines require synchronous opening of the throttle valve Through tolerances in the intake system, adjustment of the throttle valve stop is not sufficient. Dynamic adjustment is required her. Through synchronisation, the same vacuum is reached before the carburettors. A dial is required for each carburettor for synchronisation. Adjustment of the individual compressors is done via the adjustment mechanisms.
