Ignition Coil Replacement On A Lawn Mower Small Engine

by Jeremy HIPA 05 Dec 2022 0 Comments

This blog is a step-by-step instruction for replacing the ignition coil on a lawn mower. The most common reasons for replacing the ignition coil is when the engine won’t start or is hard to start.


Before you begin the replacement, you need to make sure the engine has cooled and remove the wire and boot from the spark plug to prevent the engine from accidentally starting.
Step 1: Your first step is to remove the starter rope from the rope guide. Next remove the screws to release the engine cover. Feed the starter handle through the cover and set the cover aside.
Step 2: Now remove the screws securing the gas tank and move the gas tank aside. You need to be aware that some gasoline may spill out. Next remove the mounting screw securing the dip stick tub and remove the two from the engine. Keep in mind that some engine oil may spill.
Step 3: Remove the bolts securing the blower housing and pull the housing off.
Step 4: Remove the retaining screws to release the old ignition coil. Disconnect the grounding wire and remove the old coil.
Step 5: Prepare the new ignition coil for installation by attaching the provided spark plug boot or transferring the boot from the old coil to the new one. Attach the grounding wire, seat the coil and insert the mounting screws. Use the provided instruction tag to position the coil the correct distance from the flywheel. Then secure the screws, position the blower housing on the engine and secure the bolts. Carefully insert the dip stick tube into the engine and secure the mounting screw.
Step 6: Reposition the gas tank and reinstall the screws. Feed the starter handle through the engine cover then align the cover and secure it with the screws. At last, loop the starter rope onto the guide.
With the repair completed, reattach the wire in boot to the spark plug, refill the fuel tank and your engine should be ready for use.
