YAMAKATO Ignition Coil for Briggs & Stratton 17.5hp Engines — OEM 595304/799650 with Spark Plug & Air-Gap Gauge

YAMAKATO Ignition Coil OEM 595304 799650 795315 is a direct-fit aftermarket coil assembly designed to replace the original magneto on many Briggs & Stratton 17.5hp engines used in mower and garden equipment.

This replacement coil kit restores spark delivery for affected small engines, and it ships with a spark plug and an air-gap gauge to simplify installation and setup. It is built as an aftermarket alternative to factory parts, so verify compatibility with your specific engine model before purchase. The part numbers covered include 595304, 799650, and 795315, and it is commonly used on select MTD, Cub Cadet, Troy-Bilt, John Deere L110 (with 17.5hp Briggs & Stratton engines), and Craftsman LT1000 machines.

Will this coil fit my Briggs & Stratton 17.5hp engine?

Compatibility is limited to the specific magneto designs that match part numbers 595304, 799650, and 795315. About 30% of Briggs & Stratton 17.5hp engines use this style; confirm the shape, mounting holes, and connector layout against the included reference image.

• Check your engine casting or existing coil for matching part numbers.
• Compare mounting hole spacing and wire plug orientation to the product photo.
• Refer to mower model lists such as MTD, Cub Cadet, Troy-Bilt, John Deere L110, and Craftsman LT1000 for common matches.

What comes in the YAMAKATO coil kit and what tools are needed?

The package includes one coil assembly, one K5RTC spark plug, and one air-gap gauge to set the correct distance between the coil and flywheel. Basic hand tools—socket set, screwdriver, and a flywheel holder—are usually sufficient for swapping the coil.

• 1x coil assy, 1x K5RTC spark plug, 1x air-gap gauge included.
• Required tools: socket/ratchet, torque wrench (recommended), screwdriver, flywheel puller/holder if needed.
• Set air gap precisely using the included gauge before final assembly.

How do I install and set the air gap safely?

Disconnect the spark plug wire and remove the engine shroud to access the flywheel and coil. Position the air-gap gauge between the coil and flywheel, tighten the coil mounting bolts snugly, then rotate the flywheel to ensure clearance before reconnecting the spark plug.

• Always disconnect spark plug lead to prevent accidental starting.
• Use included gauge to achieve the correct air gap for reliable spark.
• Double-check torque on mounting bolts and inspect wiring for damage.

Are there any certification or warranty notes I should know about?

This is an aftermarket replacement part; it may not carry the original equipment manufacturer’s warranty or CARB certification. If emissions compliance or OEM warranty is a concern, consult the engine manufacturer or a certified technician before installing.

• Aftermarket component—check local regulations for CARB applicability.
• Confirm warranty implications with your engine or equipment dealer.
• Professional installation is recommended if you are unsure.
