Aueomobiis Editor:
! am having trouble with valve
springs. which cause the motor to
miss every once and a while. Can
you give me any information as to
how strong the valve springs should
be? MARTIN WILTON.
Valve springs should be Just strong
enough to hold the valve firmly
against the seat and TO return II TO
Q closed position at the maximum
speed Of the motor Just a. soon ~ the
cam roller leaves the raised position
ef the valvs operating cam. valve
springs are too strong, considerable
power will be consumed In raising
them, whereas " too weak the valve
operation and consequently the en-
cine action will be srratie.
