3-38 ENGINE
VALVE SPRING
The force of the coil spring keeps the valve seat tight. Weak-
ened spring results in reduced engine power output, and often
accounts for the chattering noise coming from the valve mecha-
nism.
Inspect the valve spring for proper strength by measuring its free
length and also by the force required to compress it.
If the spring length is less than the service limit, or if the force
required to compress the spring does not fall within the range
specified, replace the spring.
