Primary Slow Mixture Cut-Off Solenoid Valve
The primary slow mixture cut-off solenoid valve is provided to cut-off the idle mixture passage between the fuel/air passage and bypass port for preventing run-on when the ignition switch is turned off.
The solenoid valve also functions to cut-off the mixture flow under deceleration.
Warning:
- Wipe up any spilled gasoline before testing.
- If cut-off valve is removed for testing, be sure you ground it to prevent sparking or fire when the key is turned on.
