CarbMate – Carburetor / Fuel injection throttle body Synchronizer


CarbMate, the cost-effective electronic replacement for mercury sticks, with the advantage of solid state electronic measurement that don’t break if you drop it.
CarbMate displays the difference in vacuum intake settings of two separate carburetors (or fuel injection throttle valves) on the same engine very precisely on a single transverse “East-West” 9 fixed resolution LED display. A single green LED at the dead-centre “happy face” mark indicates that the compared manifold vacuums are equal to within the selected resolution.

Adjustable resolution accuracy of 2 – 0.5cmHg,  0.5cmHg as recommended by motorcycle and outboard marine OEs.
