ignition breaker points. Touch one test prod to
the breaker box terminal to which the coil lead is
connected and touch the other test prod to a
good ground on the engine.
2. Turn crankshaft against rotation (counterclock-
wise) until the points close. Then slowly turn the
crankshaft with rotation (clockwise).
3. The lamp should go out just as the points break
which is the time at which ignition occurs (19°
BTC).
4. If timing needs adjustment, loosen the mounting
screws on the breaker box and move left to
advance or right to retard the timing.
