What installation and troubleshooting steps should you follow?

Installation is straightforward for someone comfortable with basic small-engine work: disconnect the battery, remove the old solenoid, transfer any mounting hardware, and reconnect wiring. If the engine continues to run after shutdown or leaks, confirm wiring polarity, terminal cleanliness and that the unit fully seats against the carburetor fuel passage.

• Disconnect power before removing the old solenoid to avoid short circuits
• Compare terminal and mounting hole locations to ensure direct fit
• Clean electrical contacts and test with multimeter for continuity when energized

This solenoid is sold as an aftermarket replacement part—always verify the part number on your existing solenoid or carburetor manual to ensure compatibility. If you’re unsure, compare photos and measurements or contact the seller with your machine model and serial number for confirmation.
