Spark Plug; Flywheel Brake Inspection - Troy-Bilt A00 Series Operator's Manual

Cleaning
1. Tap the filter several times on a hard surface to remove dirt, or
blow compressed air not exceeding 30 psi (207 kPa) through the
filter from the clean side that faces the engine. Never try to brush
off dirt. Brushing will force dirt into the fibers.
2. Wipe dirt from the air cleaner body and cover using a moist rag. Be
careful to prevent dirt from entering the air duct that leads to the
carburetor.

SPARK PLUG

Recommended Spark Plug:
NGK - BPR6ES Pressure washer applications
NGK - BPR5ES All other applications
The recommended spark plug is the correct heat range for normal
engine operating temperatures.
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 cap from
the spark plug, and
remove any dirt from the
spark plug area.
2. Use the proper size spark
plug wrench to remove
the spark plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the
sealing washer is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.028 ~ 0.030 in (0.70 ~ 0.80 mm).
If adjustment is needed, correct the
gap by carefully bending the side
electrode.
5. Install the spark plug carefully, by
hand, to avoid cross-threading.
6. After the spark plug is seated,
tighten with the proper size spark
plug wrench to compress the
washer.
When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8 ~ 1/4 turn
after the spark plug seats to compress the washer.
NOTICE
Properly tighten the spark plug. A loose spark plug can become
very hot and can damage the engine. Overtightening the spark
plug can damage the threads in the cylinder head.
7. Attach the spark plug cap to the spark plug.
