Chikia Ignition Coil for Craftsman MTD Troy-Bilt – Direct-Fit 751-12220 / 951-12220 for Powermore 420cc, OEM Mounting

Chikia ignition coil 751-12220 / 951-12220 is a direct-fit replacement coil designed to restore reliable spark to compatible Craftsman, MTD and Troy-Bilt lawn tractor engines.

If your Powermore 420 cc or compatible MTD 4P90-series engine is hard to start, stalls, or runs inconsistently, a worn or failed ignition coil is a common cause. This Chikia unit is manufactured to match the electrical and mounting characteristics of the original 751-12220 / 951-12220 parts, offering a plug-and-play option for DIY repair or professional service. It ships as a single ignition coil and is intended for a range of lawn tractors and rear-engine riding mowers where the OEM part numbers are specified.

How does swapping this ignition coil affect starting and performance?

Replacing a failing coil often restores consistent spark timing and stronger ignition, improving cold starts and steady idling. A functioning coil reduces misfires and helps the engine reach full power more reliably under load.

• Delivers the spark intensity needed for proper combustion at startup and under throttle.
• Helps prevent intermittent stalling tied to weak or erratic ignition.
• Matches OEM mounting and lead positions for straightforward installation.

What should I check before ordering to ensure compatibility?

Confirming your engine part number or the OEM coil number prevents misorders. Compare the original coil's mounting holes, electrical connector style, and part numbers (751-12220 or 951-12220) against your current unit before purchasing.

• Verify the engine model (Powermore 420 cc or MTD 4P90-series) stamped on the engine housing.
• Match existing coil part numbers: 751-12220 or 951-12220 for direct replacement.
• Inspect connector and physical mounting points to ensure fitment alignment.

What comes in the package and what tools will I need to install it?

The package contains one Chikia 1p90f/p ignition coil ready for installation. Basic hand tools and common small-engine safety steps are typically all that’s required to replace the coil yourself.

• Package includes: 1 x Chikia ignition coil (1p90f/p).
• Suggested tools: socket set, screwdriver, torque wrench (if specified by engine manual), spark plug boot puller optional.
• Recommended steps: disconnect battery or spark plug, note ignition timing marks, and refer to engine service manual.

Who is this for: This Chikia ignition coil is intended for homeowners, landscapers, and small-engine technicians who maintain Craftsman, MTD, Yard-Machines or Troy-Bilt lawn tractors and rear-engine mowers that use the listed Powermore 420 cc or 4P90-series engines. It’s suited to anyone seeking a cost-effective, direct-fit replacement part to resolve ignition-related starting and running issues without sourcing an OEM coil.
