Spark Plug Replacement

See Figure 17.
This engine uses a RCJ6Y or RCJ4 spark plug. Use an exact
replacement every 25 hours or annually.
1. Remove the spark plug boot.
2. Loosen the spark plug by turning it counterclockwise
with a socket.
3. Remove the spark plug.
4. Inspect the new spark plug. The spark plug must
be properly gapped and free of deposits in order to
ensure proper engine operation. The correct gap is
approximately 0.025 in. (0.64 mm). To widen gap, if
necessary, carefully bend the ground (top) electrode.
To lessen gap, gently tap ground electrode on a hard
surface.
5. Hand thread the new spark plug into the cylinder , turn-
ing it clockwise.
6. Tighten with a socket. (torque to 170 in.lb. [19.21 Nm]
minimum, 190 in.lb. [21.47 Nm] maximum.) Do not
over-tighten.
NOTICE:
Be careful not to cross-thread the spark plug.
Cross-threading will seriously damage the
product.
