Loose spark plugs can overheat
and damage the engine.
Overtightening the spark plugs
can damage the threads in the
cylinder head.
Install the spark plugs carefully,
by hand, to avoid cross-threading.
After each spark plug seats, tighten
with a spark plug wrench supplied
in the tool kit to compress the
sealing washer.
If reinstalling used spark plugs,
tighten 1/8 - 1/4 turn after the
spark plugs seat.
If installing new spark plugs,
tighten 1/2 turn after the spark
plugs seat.
Attach the spark plug caps. Each
cord is marked with a number near
the spark plug cap. Match the cord
numbers with the cylinder
numbers, as shown.
