Ignition Coils for Small Engines
Custom Ignition Coils for Lawn Equipment, Generators and Outdoor Machinery
A lawn mower that won’t start on a Tuesday morning. A generator that dies six hours into a storm outage. A chainsaw that sputters at full throttle. A leaf blower that won’t fire up after sitting over winter. These machines have one thing in common: the ignition coil failed.
Small engines run on precision timing. The ignition coil converts the magneto’s low voltage into the high-voltage spark that fires the spark plug at exactly the right moment. When that coil degrades, cracks or loses its winding integrity, the engine won’t start, won’t stay running or loses power under load.
For over 50 years, Custom Magnetics has designed and manufactured custom ignition coils for small engines in the harshest operating conditions. From residential lawn equipment to commercial landscaping fleets, from home standby generators to job site power, we supply the magnetic components that keep outdoor power equipment running season after season.
Ignition Coils for Lawn Equipment
Walk-behind mowers, zero-turn riders, garden tractors and commercial stand-on makers all depend on reliable ignition. These engines face dust, grass clippings, moisture and constant vibration hour after hour.
Off-the-shelf replacement coils often fail to match the original specifications, resulting in weak spark, poor timing or premature failure. Custom Magnetics designs lawn equipment ignition coils that match the exact voltage, dwell angle and spark timing of the original engine platform.
Our coils are fully potted to resist moisture and debris ingress, with precision-ground lamination stacks for consistent air gap and insulated secondary windings for high-temperature operation under engine shrouds.
Ignition Coils for Outdoor Power Machinery
Chainsaws, string trimmers, leaf blowers, hedge trimmers and brush cutters push small engines to their limits. High RPMs, frequent starting and stopping and exposure to dirt, sawdust and fuel residue all shorten ignition coil life.
These handheld and backpack applications demand lightweight and compact coil designs that still deliver hot consistent spark. Custom Magnetics manufactures small-form-factor ignition coils with optimized core geometry for tight engine housings.
We support chainsaws (professional and consumer grade), string trimmers and brush cutters, leaf blowers, hedge trimmers, and pressure washers. Our coils feature precision-wound secondary sections for high voltage output at high RPM, plus rugged terminal connections that withstand flexing and pull force.
Reverse Engineering for Obsolete Small Engines
One of the biggest frustrations in the outdoor power equipment industry is finding replacement ignition coils for older engines. Manufacturers discontinue parts. Engines change platforms. Old stock dries up.
Custom Magnetics solves this with reverse engineering services for obsolete small engine coils. Send us your failed or unusable ignition coil and we will analyze core and lamination construction, measure primary and secondary resistance, document winding direction and turn count, map mounting hole spacing and core geometry, and test spark energy characteristics.
From that analysis, we produce a new ignition coil that matches the original form, fit and function.
