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 disconnecttachometer.
