TROUBLESHOOTING
Splashed Deposits
Spotted deposits, which sometimes occur after long delayed tune-up, accumulate after a
long period of misfiring. When normal combustion temperatures are restored, upon installa-
tion of new plugs, deposits loosen from top of piston and head and are thrown against hot
insulator. Clean and service plugs and reinstall.

Mechanical Damage
Mechanical damage to spark plug firing end is caused by foreign object in combustion
chamber. Because of valve overlap, small objects can travel from one cylinder to another.
Check all cylinders, intake manifold and exhaust material to prevent further damage.
