If the pressure is low, check the following:
-Inadequate valve clearance adjustment
-Valve leakage
-Leakage from the cylinder head gasket
-Piston/cylinder worn
●
If pressure is high, check the following:
-Carbon deposits on the piston head, and cylinder head.
•
Make sure there is no dirt or debris on the seat of the
spark plug hole before inserting the spark plug.
•
To prevent damage to the cylinder head, hand-
tighten the spark plug before using a wrench to
