Fuel Cut System

Install tachometer. Tachometer must be connected to proper terminals. See IDLE SPEED & MIXTURE in ADJUSTMENTS article in the ENGINE PERFORMANCE Section.
CAUTION: Some tachometers may not be compatible with ignition system. Consult tachometer manufacturer before connecting tachometer to system. To avoid possible damage to ignitor and/or coil, DO NOT allow tachometer terminal to become grounded.
Start engine and warm to normal operating temperature. Ensure all accessories are off. Gradually increase engine RPM to at least 2500 RPM.
Using stethoscope, check for fuel injector operating sound. Ensure when throttle lever is released, fuel injector stops operating momentarily (fuel cut RPM) and then resumes operating (fuel return RPM).
Ensure fuel return RPM is within specification. See FUEL CUT SYSTEM SPECIFICATIONS table. Shut engine off and disconnect tachometer.
