Spark Arrestor Replacement On A Leaf Blower
This blog is a step-by-step instruction for replacing the spark arrestor on an Echo leaf blower. The most common reasons for replacing the spark arrestor are when the engine stops after a few seconds or won’t start at all.
Replacement
Before you begin the replacement, you need to make sure the engine and muffler have cooled and the on/off switch is in the off position. You also need to remove the wire and boot from the spark plug to prevent the engine from accidentally starting.
Step 1: Now use a t25 Torx bit screwdriver to unthread the mounting screws securing the engine cover. With the screws removed, carefully detach the cover.
Step 2: Remove the blower tube from the housing. Use the t25 Torx bit screwdriver to unthread the screws securing the exhaust deflector and spark arrestor assembly. Remove the cover guide and deflector and you can now remove the old spark arrestor if still intact.
Step 3: Install the new spark arrestor by aligning it on the muffler with the beveled edge facing inward. Align the guide on the exhaust deflector followed by the cover position the assembly on the muffler then rethread and tighten the screws to secure.
Step 4: Reinstall the blower tube and confirm that the throttle linkage is in place then realign the engine cover. Replace the mounting screws to secure the cover.
Step 5: Rethread the spark plug and be careful not to strip the threads by over-tightening. Reattach the wire in boot to the plug.
With the repair completed, turn the on/off switch to the on position and your leaf blower should be ready for use.
