maximum efficiency from the ignition, while some vehicles equipped with
emission control devices will have a retarded ignition to reduce pollution.
Adjusting the ignition distributor will change the engine timing. Timing marks
may be found on the engine vibration damper or the fan pulley at the lower front
part of the engine. Older style engines the mark is found on the flywheel (see
bottom of Fig. 1).
WHEN TO CHECK TIMING
Problems with ignition system's spark plugs or breaker points on an older
engine can cause a timing misfire. This can occur due normal wear on the
components that will eventually require replacement.
Replacing engine components in the ignition system may also require you to
reset the timing. The new component's setting or configuration out of the box
may be incorrect for your engine.
GENERAL OPERATING PROCEDURES
WARNING! Keep any part of your body or tools away from moving engine
parts when using this tool. The stroboscopic nature of the timing light will
make parts appear to move slowly or not at all. Amputation or a grevious
injury may result in contacting the engine part.
1. Locate the engine timing mark (see bottom of Fig. 1). Clean the area
around the mark and pointer of all grease and dirt. Chalk or white paint
added to the marks may make them easier to see.
2. Check the manufacturer's specifications for correct timing for the engine
being serviced. The timing specifications may be found in the vehicle or
engine manual, or on a decal beneath the car hood. This information
normally includes the Ignition Timing, Spark Plug Gap, Dwell and Idle Speed.
a. There may also be other instructions on what vehicle systems should
be shut off or turned on during the test. Follow these instructions.
3. Run the engine approximately 15 minutes or until the engine's normal
operating temperature is reached, then stop the engine.
4. Locate the vacuum line connected to the ignition distributor advance.
Disconnect and plug the line if the vehicle/engine specifications require it.
