How does the coil improve starting and performance?

By generating the required high-voltage pulse to the spark plug, a healthy ignition coil ensures consistent combustion and dependable starts. Replacing a weak or failed coil eliminates intermittent misfires, hard starting, and poor idle that result from weak spark.

• Restores strong spark for reliable cold and hot starts
• Reduces misfires, rough idling and stumbling during acceleration
• Maintains correct firing timing when installed per original specs
• Direct-fit design minimizes adjustment and modification

What should you check before replacing the coil?

Confirming compatibility and inspecting surrounding ignition components helps avoid unnecessary replacements. Check part numbers, the engine’s model plate, and wiring condition before installing the new coil.

• Verify engine model and OEM part number (751-12220 / 951-12220)
• Inspect spark plug, plug boot, and kill switch wiring for damage
• Check air gap between coil and flywheel per engine manual
• Ensure battery or starter is functioning for electric-start models

How easy is installation and what comes in the package?

Installation is straightforward for mechanically inclined users with basic tools. The QYMOTO coil ships as a single unit and bolts into the original mounting location, using the existing hardware and wiring harness.

• Package includes: 1 x QYMOTO ignition coil (951-12220 / 751-12220 replacement)
