HZ Ignition Coil for Lawn-Boy/Toro & Briggs Engines — Direct-Fit Replacement (99-2911/99-2916) Restores Spark

HZ ignition coil designed to replace Lawn-Boy and Toro part numbers like 99-2911, 99-2916 and B&S 801268 — restoring spark to compatible walk-behind mowers and snowthrowers.

If your Lawn-Boy or Toro engine is misfiring, hard to start, or cutting out under load, a faulty ignition coil is a frequent cause. This HZ coil is manufactured to match the fit and electrical output of the original Lawn-Boy gold and silver series magneto assemblies and many Briggs & Stratton-equipped engines. It is intended as a direct-fit replacement for a long list of model numbers, offering an economical way to return an aging mower or snowthrower to reliable operation without buying a new engine.

Which mower and engine models will this HZ ignition coil fit?

This coil is made to replace Lawn-Boy and Toro coils across many product lines. It lists direct compatibility with Lawn-Boy model families (gold and silver series), several Toro CCR snowthrowers, and numerous Briggs & Stratton engine codes that use the same magneto footprint.

• Direct Lawn-Boy part numbers: 99-2911, 99-2916, 92-1152, 684048, 684049.
• Common Lawn-Boy model ranges: 10201–10591, 10600–11003, 22260–22261 and related series.
• Briggs & Stratton cross-reference: replaces 801268 for engine types 084132, 084133, 084232, 084233, 084332, 084333.
• Toro compatibility: fits selected CCR2400/CCR2450/CCR2500/CCR3600 series and some snowthrower engines.

How does this ignition coil improve starting and engine performance?

A functioning ignition coil provides the high-voltage spark required for combustion on every stroke. Replacing a weak or broken coil restores consistent spark timing and intensity, which helps engines start easier, run smoothly at idle and under load, and avoid stalling during mowing or snow removal.

• Delivers steady high-voltage output to spark plug for reliable ignition.
• Helps eliminate intermittent misfires and hard-start conditions.
• Restores correct timing when paired with the original flywheel/armature.
• Durable construction reduces premature failure under normal use.

What should I check before installing the replacement coil?

Confirm fit and wiring before assembly to prevent damage and ensure safety. Inspect the flywheel key, mounting bolts, ground connections, and plug wires; damaged components can mimic coil failure and should be repaired or replaced as needed.

• Verify part numbers and engine model compatibility against your mower's ID plate.
• Inspect the flywheel key and magneto mounting surface for damage or debris.
• Check spark plug, boot, and ignition wire condition and replace if worn.
• Secure proper grounding of the coil to the engine block during installation.

Is installation difficult and what tools are needed?

Installation is straightforward for anyone comfortable with small-engine maintenance and a few hand tools. Typical steps include removing the flywheel cover, disconnecting the old coil, mounting the new coil, setting the air gap, and reconnecting the spark plug lead.

• Common tools: socket set, flywheel puller (if needed), feeler gauge for gap setting.
• Typical time: 20–45 minutes depending on access and model.
• Follow torque specifications and safety practices (spark plug removed) when working.
• Refer to your engine/service manual for exact air-gap and torque values.

Who is this for: This HZ ignition coil is aimed at DIY small-engine owners, lawn care technicians, and anyone servicing older Lawn-Boy or compatible Toro machines powered by Briggs & Stratton-style engines. If you need a direct-fit replacement for common Lawn-Boy part numbers like 99-2911 / 99-2916 or a cross-reference for B&S 801268, this coil provides a practical, budget-friendly option to get equipment back to dependable operation.
