YAMAKATO Ignition Coil Set for Briggs & Stratton V-Twin – 2-Coil Pack with 0.3mm Air-Gap Gauge

Which Briggs & Stratton models will this coil fit?

The YAMAKATO coils are compatible with many Briggs & Stratton V-Twin engines that use part numbers like 592846, 799651, 473177 and 691060. It may also replace other referenced numbers such as 401577 and several older or cross-referenced part IDs; however, fitment depends on your engine’s case layout and kill-switch connector position.

• Direct cross-references: 592846, 799651, 473177, 691060, 401577
• Additional possible replacements: 845126, 843327, 843860, 592376
• May fit selected 543000, 611000, 613000, 401000, 405000, 407000 series engines
• Always verify against your old coil dimensions and mounting hole spacing

How do I install these coils and set the gap correctly?

Installation follows standard ignition coil replacement steps: remove the old coil, mount the new coil using original bolts, and position the air-gap gauge between the coil and flywheel. The kit includes a 0.3 mm gauge for the correct gap; secure the coil, torque the bolts to the manufacturer’s specification, and reconnect the kill wire and spark plug leads.

• Use the included 0.3 mm air-gap gauge for proper spacing
• Check for grounding of the kill wire; file head fins only if necessary for clearance
• Reconfirm wiring orientation and plug boot seating before test-start
• Follow safety steps: disconnect spark plug wire during installation

What should I check if the coil doesn’t fit or fires intermittently?

If you encounter fit issues, first compare the old coil’s mounting footprint and the kill-wire connector location to the new unit. Some engines have close-fitting cylinder head fins that can press the kill wire; light filing of fins may be needed for clearance, but proceed carefully to avoid engine damage.

• Confirm bolt hole spacing and coil casing thickness match the original
• Inspect kill wire connector routing to prevent it touching ground surfaces
• If necessary, remove small amounts of fin material for clearance—do this sparingly
• Test with a known-good spark plug to isolate ignition issues

This is an aftermarket replacement part; it provides a practical repair route for many Briggs & Stratton V-Twin small engines but is not an OEM component. If you require factory warranty coverage or CARB certification for emissions, consult the engine manufacturer or a certified dealer before purchase. Professional installation is recommended for users unfamiliar with engine ignition systems.

Who is this for? If you maintain or repair ride-on mowers, garden tractors, or other outdoor power equipment with Briggs & Stratton V-Twin Intek engines and you need an affordable replacement ignition coil set with an included gap gauge, this YAMAKATO kit is a suitable option. It’s aimed at DIY mechanics, small repair shops, and owners who can verify cross-reference numbers and perform basic ignition adjustments safely.
