The first group includes the adjustments which are recommended as
necessary every spring and fall or every 10,000 miles. The second
group has the lubrication of those engine units which do not require
attention every 2,000 miles. The last part of the Tune-N-Test covers
checking and testing the ignition, compression, and carburetion sys-
tems for indications of malfunction.
TUNE-UP ADJUSTMENT GROUP
1. Clean and space spark plugs (spark plug gap .033'-.038').
2. Inspect distributor points (breaker contact gap. 016').
3. Set timing.
4. Adjust carburetor Idle speed and mixture.
MINOR MAINTENANCE AND LUBRICATION GROUP
1. Add distilled water to battery.
2. Wipe external parts of spark plugs, distributor cap, coil terminal

3. Clean and re-oil carburetor air cleaner, oil filler and ventilator caps
and ventilator outlet.
4. Torque intake manifold nuts and inspect exhaust system.
5. Adjust fan and power steering belts.
DIAGNOSIS GROUP
By purchasing the complete Tune-N"Test rather than having the
individual operations performed at separate times, a saving is achieved
by eliminating overlapping or duplicating operations.
The Tune-N-Test checks and test eliminate "guesswork" errors in
diagnosis. These tests also help avoid starting difficulty in cold weather
or trouble on the road by finding indications of impending trouble
before it occurs.
Engine Compression-Compression in your engine is the squeez-
ing of the air-fuel mixture in the cylinder.
Keeping compression at its maximum and equalized in all cylinders
insures smooth powerful operation. The tests in the compression
section check the compression in each cylinder and tell you the con-
dition of the piston rings and valves.
Electrical-The electrical system in your car is like a miniature
electrical plant that serves a city. The generator and charging circuit
