OPERATION

ENGINE TIMING

Timing is defined as the ignition of fuel in the engine cylinder when the piston is

Top Dead Center (TDC) during the engine cycle (Fig. 1). Timing is given in

degrees Before Top Dead Center (BTDC) or After Top Dead Center (ATDC).

Consult the engine manufacturer's timing specifications.

Engine component or ignition system wear can affect the engine timing. The

ignition occurs BTDC or ATDC, generates less mechanical energy and results in

poorer fuel economy. When the spark plug ignition is responsible, this is

referred to as Spark Advance or Spark Retard respectively. Some engines are

designed so the timing spark will occur several degrees before TDC to obtain

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.

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 PROCEDURE

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.

The tool has multiple functions. Follow the general operating procedure when

performing a task, but use the alternate steps for specific function. See the

specific tasks following this section.

1. Locate the engine timing mark. 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.

a. The timing mark may be a line in older vehicles or a timing tape

displaying the number of degrees on newer vehicles.

2. Check the manufacturer's specifications for the engine being serviced. The

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 be other instructions on what vehicle systems should be

shut off or turned on during the test. Follow these instructions.

3. Run the engine until the engine’s normal operating temperature is reached,

then stop the engine.

4. Push the lead (E or F) connector into the

sensor connector (D3).

5. Connect the tool’s black negative clamp

(-) to the negative battery terminal and

the red positive clamp (+) to the

battery’s positive terminal (see Fig. 2).

6. Start the engine and operate at normal

idle speed.

7. Press the button (L) to select the

function (H to K).

a. Advance has two options. The

decimal point in the LCD (G) will

flash when set for a 2-stroke engine

or direct-ignition systems. The dot remains solid for a 4-strike engine.

8. Aim the timing light (A) so it will illuminate the timing mark and press

the trigger.

9. Follow the steps listed below based on the procedure.

10. Stop the engine once the task is complete.

CONNECT THE CONDUCTIVE LEAD

1. Connect the inductive lead (F) to the spark plug lead on cylinder number 1

(Fig. 2). The arrow on the clamp must point towards the spark plug for the

tool to work correctly. The clamp will detect the electrical pulse to the spark

plug during the engine cycle.

a. Some distribution system have a positive earth. If the strobe light does

not work, turn the clamp around to point towards the distributor.

2. Locate the vacuum line connected to the ignition distributor advance.

Disconnect and plug the line if the vehicle/engine specifications require it.

Insert a plug into the vacuum port.

ADJUSTING TIMING TO SPECIFICATIONS

Checking the idle timing determines if the cylinder is at Top Dead Center during

the engine cycle.

1. Connect the conductive lead.

2. The pointer will align with the timing mark or align with the correct degree

number if the idle is set correctly.

3. Advance the timing when the timing mark is above (to the left) of the pointer

or the degree number is less than the manufacturer’s recommendation.

4. Retard the timing when the timing mark is below (to the right) of the pointer or

the degree number is more than the manufacturer’s recommendation.

5. Loosen the bolt located at base of the distributor, but do not remove it. The

bolt must be loose enough to rotate the distributor back and forth by hand,

but not enough that the distributor can rotate by itself.

6. Start the engine.

7. Direct the timing light at the timing marks so the pointer is visible and

stationary. Slowly rotate the distributor right and left until the pointer aligns

with the TDC indicator on the timing marks.

a. Advance the timing by turning the distributor counterclockwise.

b. Retard the timing by turning the distributor clockwise.

8. Tighten the bolt at the distributor’s base without changing the

distributor’s position.

9. Restart engine and recheck the timing is correct.

10. Once the timing is correct, remove the vacuum plug and reinsert the

vacuum hose.

CHECKING VACUUM ADVANCE

1. Connect the conductive lead.

2. Increase the engine speed to 2,000 RPM.

a. A second person or a pedal depressor may be necessary if the choke

lever is difficult or unsafe to manipulate while taking a timing reading.

3. Squeeze the trigger to activate the timing light. Slowly rotate the knob on

the side of the timing light gun (A), stopping when the pointer centers on

TDC or the timing tapes 0 mark.

4. Observe the reading from the LCD (G) and compare with the manufacturer's

specifications. Follow the engine manufacturer’s instructions to adjust the

advance.

TESTING CENTRIFUGAL ADVANCE

The centrifugal advance tests if the distributor’s mechanical mechanism will

cause each piston’s spark plug to fire earlier as the engine’s RPM increases.

1. Connect the conductive lead.

2. Speed the engine up slowly and watch the timing mark.

3. The timing mark should remain stationary until the engine reaches the

manufacturer's specified speed. The timing mark should then move

steadily and without jerking.

4. Reduce the engine speed and the mark should move steadily back.

5. Service the centrifugal (automatic) advance if the mark does not move or if

it moves erratically,

6. To check the maximum advance, it is necessary to mark the harmonic

balancer with the maximum degree per manufacturer's specifications and

follow manufacturer's procedures.

TESTING VACUUM ADVANCE

The vacuum advance tests if the distributor’s vacuum mechanism will

cause each piston’s spark plug to fire earlier as the engine’s RPM increases.

The engine timing light remains connected and the vacuum line must be

properly installed.

1. Follow Step 1 in connect the conductive lead. Reconnect the vacuum tube

if it was disconnected for another task.

2. Set the engine speed fast enough to apply vacuum to the distributor.

3. Aim the timing light and note the position of the pointer.

4. Disconnect the vacuum line and the pointer should move.

5. The distributor should be serviced if the pointer does not move. The trouble

may be a plugged line, a leaky diaphragm or a frozen distributor plate.

DWELL ANGLE MEASUREMENT

1. Follow Step 1 in connect the conductive lead. Reconnect the vacuum tube

if it was disconnected for another task.

2. Press the button (L) to select the dwell angle (J).

3. Connect the green test clip (D4) to the

ignition coil’s terminal 1 (Fig. 3-1).

4 Start the engine and let it run at idling

speed.

5. Read the dwell angle reading in % from the

LCD and compare it with the verhicle

manufacturer's recommendations.Refer to

the Dwell Angle conversion table in

Appendix A.

6. A smaller than expected dwell angle

indicates the point gap is too large. A larger

than expected dwell angle indicated the

point gap is too small. Adjust the gap as required.

CHECKING DISTRIBUTOR CAM WEAR

Testing for wear in the distributor cam ensures that the timing is correct for the

even numbered cylinders that ignite while the odd numbered cylinders are at the

bottom of their cycle stroke.

1. Ensure that the timing for cylinder number 1 is set and the pointer aligns

with the correct timing mark lines.

2. Connect the timing light to the wire directly opposite (180°) cylinder

number 1 on the distributor cap.

3. Start the engine and aim the timing light towards the timing mark. The

reading should be the same as when connected to cylinder number 1.

4. If the reading is not the same, the probable cause is a worn out distributor

cam or bent distributor shaft. Repair as required.

TACHOMETER

1. Follow Step 1 in connect the conductive lead. Reconnect the vacuum tube

if it was disconnected for another task.

2. Press the button (L) and select RPM (I).

3. Start the engine and read the RPM from the LCD.

4. Compare the reading to the manufacturer’s recommended RPM and adjust

any calculations are necessary.
