The spark plug(s)

The spark plug(s) should be checked, cleaned and re-
gapped on a monthly basis or every 100 hours of use.
The plugs should be replaced every six months or 300
hours of use.
When checking the spark plug(s), a dry, light colored
residue on the plugs is a sign of running lean. Check
the fuel mixture and adjust the carburetor.
If there is a thick, wet, black residue on the plug the
engine is running rich. Check the fuel mixture and
adjust the carburetor.
There should be a dry tan coating on the plug(s). this
would indicate the proper mixture.
1. To remove/replace the spark plug(s):
1a. Remove the spark plug wire(s).
See Figure 9.1.
NOTE: Do not use metal pliers on spark plug
wire(s). Damage to the wire can result.
