A cross-threaded or over-tightened spark plug will
damage the aluminum threads of the cylinder head.
When dismantling the spark plug, keep debris from
entering the engine via the spark plug hole.
Follow the procedure below to tighten the spark plug
properly.
Carefully turn the spark plug by hand into the threads until
it is finger tight. If the spark plug is new, tighten it with a
wrench about 1/2 turn past finger tight. If you are reusing
the old spark plug, tighten it with a wrench about 1/8 turn
past finger tight.
NOTE: Insert the plug cap completely.
