The manual you need is right here 👉 John Deere 100 Series Lawn Tractor Service & Repair Manual
It covers the Briggs & Stratton single-cylinder engine used in the JD115 and includes everything you need to replace the ignition coil properly — from removing the blower housing and flywheel to adjusting and reinstalling the new coil. Step-by-step instructions, diagrams, and torque specs are all included straight from the factory service docs.
