WATCH YOUR
VALVES.
Useful Hints.
By James F. Donahue
While proper valve action and full compression ure essential to the production of full power in an engine, their good can almost be nullified by a faulty Ignition system or improper carburetion.
These are the two essentials to maintaining the best of power.
Compression may be perfect and valve action just right, but if the spark doesn't occur at the proper time power is lost. The spark must igaile the mixture at the peak of compression, when the piston has reached the top of its compression strake and poises for the fraction of a moment before its downward sweep.
Ir the park occurs before or after the piston reaches this point, there is loss of compression and of power. Therefore the spark must be perfectly timed to occur at just the right moment in each cylinder. The breaker points of the timer must hit nccurately and the spark gn must be the width of the tmickness of a thin dime.
In the case of pre-ignition, the
