PARTSRUN Ignition Coil for Kohler CH16/CV16 Engines — Direct-Fit 12 584 14-S/17-S Replacement

PARTSRUN 12 584 14-S (ZF-IG-A00086) is a direct-fit replacement ignition coil made to restore spark performance on Kohler CH16 and CV16 lawn mower engines.

If your lawn mower is running rough, misfiring, or refusing to start, the ignition coil is one of the first parts to check. This PARTSRUN module matches Kohler OEM numbers 12 584 14-S and 12 584 17-S and is engineered as a 100% new replacement that helps re-establish the high-voltage pulse needed for consistent combustion. It’s designed to bolt in with the same mounting points and connector layout as the original, minimizing installation time and troubleshooting.

How does this ignition coil fit my Kohler engine?

The PARTSRUN coil is manufactured to match Kohler CH16 and CV16 engine specifications and is cross-referenced to OEM numbers 12 584 14-S and 12 584 17-S. It uses the same mounting footprint and electrical connector types so it installs like the original part. Wiring and orientation are preserved to avoid ignition timing shifts.

• Direct replacement for Kohler 12 584 14-S and 12 584 17-S
• Compatible with CH16 and CV16 engine models
• Same mounting holes and connector layout as OEM
• PARTSRUN part number ZF-IG-A00086 for easy sourcing

What performance improvements should I expect after installing it?

Replacing a failed or weak coil typically restores crisp starting, steadier idle, and improved throttle response by delivering a full-strength spark. It does not alter engine tuning but reinstates the intended ignition energy, reducing misfires and incomplete combustion events. For best results, pair coil replacement with a good spark plug and clean flywheel key/timing components.

• Stronger spark for reliable starts
• Reduced misfiring and smoother idle
• Compatible with existing ignition components and plug type
• Helps maintain original engine performance

How difficult is installation and what tools are needed?

Installation is straightforward for anyone comfortable with basic small-engine work. Typical steps include removing the engine cover, unplugging the old coil, unbolting the module, and installing the new coil in the same orientation. No special tools are required beyond common sockets, a screwdriver, and a torque caution to avoid overtightening.

• Basic hand tools: socket set, screwdrivers, pliers
• Approximate time: 15–30 minutes for most users
• Follow engine service manual for gap specs and torque values
• Verify ignition timing and plug gap after replacement

What should I check if the engine still has issues after replacement?

If symptoms persist after installing the PARTSRUN coil, inspect the spark plug, flywheel key, electrical connectors, and ground paths. Faulty wiring, a fouled plug, or a damaged magneto/flywheel can mimic coil failure. Confirm the new coil is seated correctly and that the air gap meets the engine manufacturer’s specification.

• Inspect and replace the spark plug if worn or fouled
• Check flywheel key for shearing or timing shifts
• Ensure coil-to-flywheel air gap matches Kohler specs
• Verify connector pins are clean and secure
