A bad ignition coil can cause many problems on chainsaws. Here is a step-by-step guide on how to replace an ignition coil on HOMELITE 42cc chainsaw.

HOW TO

Before you replace the ignition coil on your chainsaw, you need to make sure the engine has cooled first and the switch is in the off position.
Step 1: Use the t25 Torx bit screwdriver to unscrew the screws securing the top cover and pull the cover off.
Step 2: Remove the screws securing the recoil starter. You will need to remove the screws securing the left side of the chain brake handle as well and put it off.
Step 3: Take the caps off the gas and oil tank to pull the starter off. Then reinstall the fuel cap to prevent spillage.
Step 4: Remove the spark plug wire and boot from the spark plug. And now disconnect the ignition coil wire and confirm that the flywheel magnets are rotated out of the way then remove the mounting screws securing the old ignition coil to take it off.
Step 5: Install the new ignition coil by aligning it with the engine. Thread the mounting screws loosely and remember to secure the grounding wire under the upper screw. Now you can pull the coil back and tighten the screws.
Step 6:You need to insert a business card or cardboard between the coil and flywheel, then rotate the flywheel so the magnets will align with the coil. Loosen the screws to align the coil at the correct distance from the flywheel.
Step 7: Retighten the screws and remove the card. Connect the ignition coil wire to the new coil, attach the spark plug wire and boot to the spark plug.
Step 8: Unthread the gas and oil caps, reposition the recoil starter and rethread the caps. Realign the chain brake handle and secure the screw. Then you need to replace the remaining screws to secure the recoil starter. Now the last step is to realign the top cover, thread and tighten the screws to secure it.
