Ignition Timing
Set ignition timing after cam angle is set to 57-63°. With engine at normal operating temperature, connect a timing light and tachometer to engine.
CAUTION:
To avoid possible damage to alternator, do not use battery in car being tested to power timing light, use a separate car battery.
Timing at idle should be retarded the specified number of degrees which corresponds to the "F" mark on engine pulley. Maximum ignition advance should be set to specifications and corresponds to the "M" mark on engine pulley (at 5000 RPM). Adjust timing by rotating distributor housing.

| 1750 (1971) | 2° ATDC | 31-37° |
| 2000 (1972-73) | 5-7° ATDC | 27-33° |
