Spark Plug Service

Recommended spark plug: NGK - BPR5ES

NOTICE

Incorrect spark plugs can cause engine damage.

For good performance, the spark plug must be properly gapped and

free of deposits.

1. Disconnect the spark plug

cap and remove any dirt

from around the spark plug

area.

2. Remove the spark plug

with a 13/16 in (21 mm)

spark plug wrench.

3. Inspect the spark plug.

Replace it if the electrodes

are worn, or if the insulator

is cracked, chipped, or

fouled.

4. Measure the spark plug

electrode gap with a suitable

gauge. The gap should be

0.028 ~ 0.031 in (0.7 ~ 0.8 mm).

Correct the gap, if necessary,

by carefully bending the side

electrode.

5. Install the spark plug carefully,

by hand, to avoid

cross-threading.

6. After the spark plug seats,

tighten with a 13/16 in (21 mm)

spark plug wrench to compress the washer.

If reinstalling the old spark plug, tighten 1/8 to 1/4 turn after the

spark plug seats.

If installing a new spark plug, tighten 1/2 turn after the spark plug

seats to compress the sealing washer.

NOTICE

A loose spark plug can overheat and damage the engine.

Overtightening the spark plug can damage the threads in the

cylinder head.

7. Install the spark plug cap on the spark plug.

Blade Control Operation Check

Start the engine outdoors. Move the throttle lever to FAST and

release the blade control lever; the engine should stop quickly. If the

engine does not stop quickly, take the mower to an authorized Honda

servicing dealer for repair.

Spark Arrester Service (optional equipment)

Your lawn mower engine is not factory-equipped with a spark arrester.

In some areas, it is illegal to operate an engine without a spark

arrester. Check local laws and regulations. An optional USDA

approved spark arrester is available from an authorized Honda

servicing dealer.

The spark arrester must be serviced every 100 hours to keep it

functioning as designed.

1. Allow the engine to

cool and disconnect

the spark plug cap

to prevent

MUFFLER

accidental starting.

2. Remove the three

6 mm flange bolts

from the muffler

protector and

protector.

3. Remove the 4 mm

self-tapping screw

from the spark

arrester and

arrester from the

muffler. Be careful

not to damage the

screen.

4. Check for carbon deposits on the spark arrester and the exhaust

port. Use a brush to remove carbon deposits. Be careful to avoid

damaging the spark arrester screen. Replace the spark arrester if

there are any breaks or holes.

5. Install the spark arrester and muffler protector in the reverse order

of disassembly. Tighten all hardware securely.
