585836101 Ignition Module Coil for Husqvarna and Ryobi Handheld Blowers

Key Features

  • Precision Electronic Ignition: Engineered to provide a consistent, high-intensity spark across the entire RPM range, ensuring reliable starting and smooth engine performance.
  • Optimized Ignition Mapping: Specifically calibrated for small-displacement 2-stroke blower engines, improving fuel efficiency and reducing emissions during high-speed operation.
  • Weather-Shielded Encapsulation: The internal circuitry is fully potted in high-grade, heat-resistant epoxy to protect against vibration, moisture, and debris common in lawn care environments.
  • Reinforced Spark Plug Lead: Features a high-tension wire with a durable silicone boot designed to resist cracking and electrical "arching" against the engine cylinder.
  • Direct Bolt-On Fitment: Designed to the exact mounting specifications of the original factory module, facilitating a straightforward "drop-in" replacement without modifications.

Compatibility & Fitment

This ignition coil is a universal replacement for several popular handheld blower platforms. Key compatible models include:

  • Husqvarna: 125B, 125BVX, 125BX (Standard and E-series models).
  • Ryobi: Fits various 25cc and 26cc handheld blowers (e.g., RY08510, RY08544, RY08548).
  • Homelite: Compatible with many 26cc "Blower/Vac" models (e.g., UT08514, UT08544, UT08546).
  • Note: Always verify your original coil's mounting hole spacing and wire orientation, as these models occasionally used different engine suppliers.

When to Replace

  • No Spark Condition: The most common failure; the engine will not start despite having fresh fuel and a clean spark plug.
  • Stalling When Hot: The blower runs perfectly for 5–10 minutes but dies as the engine reaches operating temperature and won't restart until cooled (thermal failure).
  • Misfiring or "Stuttering": The engine hesitates at full throttle or has an inconsistent idle, indicating the coil is struggling to maintain a steady pulse.
  • Visible Insulation Damage: The spark plug wire is frayed, melted, or showing signs of being chewed by rodents, leading to a grounded ignition circuit.
  • Intermittent Kill Switch Issues: If the engine refuses to shut off or dies unexpectedly, the kill switch terminal on the coil may be shorting internally.

Installation & Timing Tips

  • The "Business Card" Gap: To ensure the strongest spark, the air gap between the coil legs and the flywheel magnets should be approximately 0.010" to 0.012". Use a standard business card as a gauge during installation.
  • Check the Ground Path: Ensure the mounting surfaces on the engine block and the coil legs are free of rust and oil. The coil grounds through its mounting bolts; a weak ground equals a weak spark.
  • Kill Switch Wiring: Be careful when attaching the small spade terminal for the stop wire. If this wire is pinched against the metal housing, the engine will never start.
  • Flywheel Magnet Cleanup: While the starter cover is off, use a rag to wipe metal shavings or sap off the flywheel magnets to ensure the strongest possible magnetic induction.
  • Spark Plug Health: It is highly recommended to install a fresh NGK BPMR7A (or equivalent) spark plug when replacing the coil to ensure the new module isn't stressed by a fouled plug.

Nice air filter
Replaced my K&N filter with this KAX filter. Same performance and better mileage.

A Great Filter (Installed on a 2014 Acura RDX)
I installed this on a 2015 Acura RDX and it has been a fine replacement for the original air filter. The filter offers a good value and resembles the filter that it replaced and seems to be an equivalent replacement in every way. It fit into the housing perfectly and was just as easy to replace as the original filter was. The white color of the filter also makes it easy to see if an excess of dirt has built up on the filter. I'd recommend this filter. The materials are good, it offers equivalent functionality, and great value for the money.

Excellent quality and price
The picture above is of two different brand engine air filters. One is a Fram Extra Guard and the other is the KAX filter, which costs half as much. Can you tell which one is the cheaper KAX filter? There may be a difference in material that is not visible, but they feel and look the same. It seems like a safe bet to try out the KAX and see how well it performs/lasts.

Just Right
Fits just right. The paper filter material seems to be the same quality as the brand name filter I took out with the only percievable difference is price and packaging. One nice thing here is that once taken out of the box, the filter is wrapped in light weight plastic so you don't get the new filter dirty when taking out the old one. Just unwrap it prior to installation for a clean install. Hope this helps.

Same Quality, Cheaper Price!
Fits exactly as it should (2018 Acura RDX) and performs as well as any other brand I've used over the years. Construction and material quality appear as good as (or better) than any other off-the-shelf brand. I have no qualms about using this brand in the future and saving money doing so, compared to other brands.
