Check the spark plug:
1. Remove the spark plug. Use a spark plug wrench to loosen the spark plug and pull it out of the cylinder head.
2. Inspect the spark plug. Look for any signs of damage, such as cracks or excessive wear on the electrodes. If the spark plug is damaged, replace it with a new one.
3. Check the spark plug gap. Use a feeler gauge to measure the gap between the electrodes. The correct gap should be specified in your owner's manual. If the gap is incorrect, adjust it by bending the ground electrode.
Check the spark plug wire:
1. Inspect the spark plug wire. Look for any damage or cracks in the wire. If the wire is damaged, replace it with a new one.
2. Check the connection between the spark plug wire and the spark plug. Make sure the wire is properly seated on the spark plug.
Check the ignition coil:
1. Remove the ignition coil. Use a wrench to loosen the bolts that hold the ignition coil in place, and then pull the coil out of the engine.
2. Inspect the ignition coil. Look for any signs of damage, such as cracks or corrosion. If the ignition coil is damaged, replace it with a new one.
3. Check the continuity of the ignition coil. Use a multimeter to test the continuity of the ignition coil. The coil should have continuity between the primary winding and the secondary winding.
Check the CDI unit (Capacitor Discharge Ignition):
1. Locate the CDI unit. The CDI unit is usually located under the seat or behind the side panel.
2. Inspect the CDI unit. Look for any signs of damage, such as cracks or corrosion. If the CDI unit is damaged, replace it with a new one.
Check the wiring:
1. Inspect the wiring. Look for any loose or damaged wires. If you find any loose wires, reconnect them. If you find any damaged wires, replace them with new wires.
Test the ignition system:
1. Reconnect all of the components that you removed.
2. Turn on the ignition. If the spark plug fires, the ignition system is working properly.
If you have checked and fixed all of the above components and the ignition system is still not working, it may be necessary to take your Honda Spree to a qualified mechanic for further diagnosis and repair.
