Spark Plug

Replace the spark plug every 2 years or after 150 hours of use.

Required Spark Plug:

 NGK - BPR5ES

NOTICE

An incorrect spark plug can cause engine damage.

For good performance, the

spark plug must be properly

gapped and free of deposits.

1. Allow the engine to cool,

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 or chipped.

4. Measure the spark plug

electrode gap with a suitable

gauge.

Gap:

 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.

Spark plug torque: 

14 ft-lb (20 N·m)

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.

Spark Arrester (optional part)

The spark arrester must be serviced every 100 hours to keep it 
functioning as designed.

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. See 

page 18

 for part numbers.

1. Allow the engine to cool and disconnect the spark plug cap.
2. Remove the three flange bolts and the heat shield. Remove the

setscrew and the spark arrester from the muffler.

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

port. Use a brush to remove any carbon deposits from the screen.

Replace the screen if it is torn or damaged.

4. Installation is the reverse of removal. Tighten all hardware

securely.

Blade Control Check

1. Start the engine outdoors.
2. Release the blade control lever; the engine should stop quickly.

If it does not, take your mower to an authorized Honda servicing

dealer for repair.
