Setup and Installation

Safety First: Before beginning any installation, ensure the equipment is turned off, cooled down, and the spark plug wire is disconnected to prevent accidental starting. Wear appropriate safety gear, including gloves and eye protection.

1. Locate the Existing Ignition System: Identify the current ignition coil and spark plug on your Husqvarna brush cutter or Poulan chainsaw.
2. Disconnect Wires: Carefully disconnect all wires connected to the old ignition coil, including the spark plug wire and any kill switch wires. Note their positions for reinstallation.
3. Remove Old Components: Unscrew and remove the old ignition coil. Use a spark plug wrench to remove the old spark plug.
4. Install New Spark Plug: Thread the new BM6A spark plug into the cylinder head by hand to avoid cross-threading. Once finger-tight, use a spark plug wrench to tighten it an additional 1/4 to 1/2 turn. Do not overtighten.
5. Mount New Ignition Coil: Position the new ignition coil module in the same location as the old one. Ensure proper alignment with the flywheel. The air gap between the coil and the flywheel is critical for proper ignition. A typical gap is around 0.010-0.014 inches (0.25-0.35 mm). A business card or feeler gauge can be used to set this gap.
6. Secure the Coil: Tighten the mounting screws for the ignition coil.
7. Connect Wires: Reconnect the spark plug wire to the new spark plug. Connect any other wires (e.g., kill switch wire) to the new ignition coil as they were on the old unit.
8. Final Check: Double-check all connections and ensure all tools are removed from the equipment.

Operating Considerations

After installing the new ignition coil and spark plug, the equipment should start and run smoothly. If you encounter issues, refer to the Troubleshooting section.

• Ensure the spark plug wire is securely attached to the spark plug.
• Verify that the kill switch wire (if applicable) is properly connected and functioning.
• Always use the correct fuel mixture for your 2-stroke engine as specified by the equipment manufacturer.

Maintenance

Regular maintenance of your ignition system components can extend their lifespan and ensure reliable performance.

• Spark Plug Inspection: Periodically remove and inspect the spark plug. Look for signs of wear, carbon buildup, or fouling. Replace if electrodes are worn or if there is heavy fouling.
• Spark Plug Gap: Check the spark plug gap with a feeler gauge and adjust if necessary to the manufacturer's specification (typically around 0.020-0.028 inches or 0.5-0.7 mm for small engines).
• Wire Connections: Ensure all electrical connections to the ignition coil and spark plug are clean, tight, and free from corrosion.
• Cleanliness: Keep the area around the ignition coil and spark plug clean and free of debris, oil, and fuel residue.
