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
The kit includes soft nylon travel case, battery cord-set, T-connector and 4 x M5 & M6 flexi-rigid manifold connection adapters

CARBMATE
Electronic two-channel synchronizer for carburetors
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
