E-curve settings.

CLEAR AS MUD....

Rotate the engine to TDC then to 12° - 15° BTDC. With the rotary switches set to "1" and "7" (These
settings will be used to start the engine and adjusted later.) install the distributor with th rotor pointing
to the number 1 spark plug wire and start the engine.
With the engine running and a timing light connected, adjust the timing to the desired Total Timing.
(Example 32° without vacuum advance) Once you've set the total timing, turn the engine off and
remove the distributor cap. Set the rotary dials to achieve the desired timing curve (Figure 3 and 4).
For example with total timing set at 32° and the rotary dials set to "2" and "9". The engine will idle
at 12°, timing will start to advance at 1,100 rpm and will be fully advanced by 3,500 rpm, plus a 15°
vacuum advance at 10 in-Hg (inches of vacuum).
