VACUUMMATE
PROFESSIONAL-GRADE ELECTRONIC FOUR-CHANNEL
THROTTLE BODY AND CARBURETOR SYNCHRONIZER
  • The industry standard for fast and precise synchronizing of 2- and 4-stroke, two-, three- and
  • four-cylinder engines (synchronizes up to six cylinders with optional adapter)
  • No fragile glass, no toxic mercury, no mechanical friction or inertia, no calibration hassles
  • Solid-state medical-grade sensors are drop-proof, and self-calibrate for barometric pressure changes
  • Shock- and water-resistant composite molded polyurethane and polycarbonate casing is strong
  • and resilient
    3804-0020
  • Vertically arranged LED bars (40 LEDs in each bar) provide clear visuals (even in sunlight)
  • of signals derived from solid-state electronic pressure sensors
  • ”RPM” mode for essential adjustment of engine speed before and after synchronizing
  • – 2- or 4-stroke switch allows correct readings on both engine types
  • Flick the switch to check rpm on channel 1 and flick to VAC to display accurate
  • vacuum readings
  • ”AVE” mode with three overlapping scale ranges 5-25, 20-40, 35-55  cm Hg for convenient
  • and quick synchronizing – precise 0.5  cm Hg resolution on all scales
  • Diagnostic mode with auto-ranging scale for immediate visual check if engine is difficult
  • to synchronize
  • Quickly checks for non-sealing intake or exhaust valves, leaking manifold or a restricted
  • air intake
  • WS (workshop) model is powered by any 12V vehicle battery or 12VDC adapter; “Low input
  • power” warning LED
  • ME (marine) model has internal rechargeable 1.5Ah 7.2V NiMH batteries; recharge by connecting
  • to a 12V vehicle battery or 12VDC adapter
  • ”Low battery” warning LED plus dual-purpose “Charge” LED that indicates external power connected and recharging in progress

  • and fuel injection
  • The cost-effective electronic replacement for mercury sticks
  • Easily converted to synchronize three or four
  • carburetors/ throttle bodies (accessory sold separately)
  • Bright color LED graph display reacts to even minor
  • adjustments quickly
  • Precision instrument that is accurate to 0.5cmHg
  • (meets or exceeds OEM specifications)
  • Solid-state electronics are shock resistant
  • and extremely durable
  • CarbMate displays the difference in vacuum intake settings
  • of two carburetors or throttle bodies very precisely on
    3804-0011
    a single transverse “East-West” 9 LED display – visual
    estimation errors, common to the traditional approach
    which is to visually compare the individual values on separate
    columns of mercury or dial gauges are eliminated as two
    pressures are compared and one value is displayed
    3804-0010
  • A single green LED at the center mark indicates that the compared
  • 3804-0019
    manifold vacuums are perfectly equal to within the selected resolution
  • A ZERO adjustment knob provides easy and quick pre-calibration prior to synchronizing;
  • with no tubes connected, simply adjust the knob until the center LED is on

  • The extended vacuum adapter includes 1 1 / 2 ’ of
  • santoprene hose and is ideal for permanent mounting
    on sportbikes or any other vehicles where access to the
    carburetor or fuel-injection synchronizing ports requires
    removal of various side panels, air filters or the fuel tank
  • The unique flexi-rigid adapter easily allows
  • synchronization of machines with difficult-to-reach 5mm or 6mm
    carburetor or fuel-injection vacuum ports; simply bend the outer sheath to the
    appropriate angle/ shape and then turn the inner tube to thread the brass fitting
    into the vacuum port
