VacuumMate Carburetor & Throttle Body Synchronizer
Professional intake synchronizer, dynamic fault analyzer, and tachometer for accurate carburetor and fuel-injection throttle-body synchronization on compatible 2- and 4-stroke engines.
The VacuumMate provides fast, accurate synchronization of carburetors and fuel-injection throttle valves while also giving technicians valuable diagnostic information. Its electronic pressure measurement system supports precise intake balancing and built-in engine-speed monitoring without requiring a separate RPM pickup.
Three selectable operating modes support synchronization and troubleshooting. RPM mode helps technicians monitor engine speed during adjustment, AVE mode provides manifold vacuum readings for general synchronization, and DYN mode helps identify conditions that can prevent proper synchronization, such as poor valve sealing or intake-manifold problems.
Key Features
- Carburetor & FI Synchronization: Designed for accurate synchronization of compatible carburetors and fuel-injection throttle valves.
- 2- & 4-Stroke Applications: Supports compatible 2-stroke and 4-stroke engine service.
- Three Diagnostic Modes: RPM, AVE, and DYN modes provide engine-speed monitoring, synchronization, and dynamic troubleshooting capability.
- Dynamic Fault Analysis: Helps identify synchronization problems such as poor valve sealing or intake-manifold faults.
- Built-In Tachometer: Measures RPM from intake pressure pulses without requiring a separate electrical pickup.
- Expandable to 6 Cylinders: Synchronize up to six cylinders with optional adapter kit 35-8114.
- Marine Service Ready: Battery-powered operation and water-resistant construction support compatible marine applications.
- Complete Adapter Set: Includes battery cord-set, T-connector, and M5 / M6 flexi-rigid manifold adapters.
