Inspecting And Replacing The Spark Plug; Replacing The Drive Belts - Toro 38631 Operator's Manual

Inspecting and Replacing the
Spark Plug
Use a Champion RJ-19LM or equivalent spark plug. Check
and gap the spark yearly, and replace the plug if necessary.
1. Clean around the base of the spark plug.
2. Remove the spark plug.
3. Examine the spark plug and replace it if it is cracked,
fouled, dirty, or if the electrodes are worn.
Important: Do not clean the electrodes because
grit could enter the cylinder and damage the
engine.
4. Set the gap between the electrodes on the spark plug at
0.030 inch (0.76 mm) (Figure 51).

5. Install the spark plug by hand and then torque it to 15
ft-lb (20.4 N·m).
Note: If you do not have a torque wrench, tighten
the plug firmly.
Adjusting the Discharge Chute
Latch
If the discharge chute does not lock into the desired
position or does not unlock so that you can move it to
another position, adjust the discharge chute latch.
1. Remove the fastener on the gear cover (Figure 52), lift
the front of the cover up, and slide it back and out of
the way.

2. Loosen the bolt on the cable clamp (Figure 53).

3. Grasp the cable conduit and move it toward the front of
the machine until the discharge chute latch fully engages
the gear teeth (Figure 53 and Figure 54).

Note: The latch is spring loaded and will naturally
move into the teeth of the gear (Figure 54).
4. Remove any slack in the cable by pulling the cable
conduit rearward.
5. Tighten the bolt on the cable clamp.
6. Install and secure the gear cover.
