Engine Tune-Up
Occasionally your serviceman will recommend an engine tune-up. The frequency of tune-ups depends almost entirely on the amount of driving and the type of driving you do. When you purchase a tune-up, we recommend that you request at least the following operations:
1. Check the manifold heater valve for free operation.
2. Clean and adjust spark plugs; install with new gaskets.
3. Clean carburetor air cleaner.
4. Clean fuel pump bowl and strainer; install with new gasket.
5. Clean inside of distributor cover, cable terminals, and sockets.
6. Tighten cylinder head cap screws to recommended tension.
7. Adjust fan belt.
8. Remove and clean carburetor choke thermostatic control. Replace with new gasket and adjust, if necessary.
9. Check and set ignition timing.
10. Adjust carburetor idle screw with engine at normal operating temperatures.
11. Adjust idle stop screw to produce engine speed corresponding with 8 miles (13 km.) per hour road speed in high gear.
