MAINTENANCE
Replacing the spark plug
1.Remove the ignition cable shoe and clean around the spark plug.
2.Remove the spark plug with a 13/16" (21 mm) spark plug socket wrench.
3.Check the spark plug.
Replace the spark plug if the electrodes are burnt or if the insulation is cracked or damaged.
Clean the spark plug with a wire brush if it is to be reused.
4.Measure the electrode gap with a gapping tool. The gap should be 0.7 - 0.8 mm / 0.030". Adjust as necessary by bending the side electrode.
5.Reinsert the spark plug, turning by hand to avoid damaging the threads.
IMPORTANT INFORMATION
Inadequately tightened spark plugs can cause overheating and damage the engine. Tightening the spark plug too much can damage the threads in the cylinder head.
6.Tighten the spark plug, once it touches the seating, with the spark plug spanner.
Tighten the spark plug so that the washer is compressed.
A used spark plug should be turned 1/8 of a turn from the seated position. A new spark plug should be turned 1/4 a turn from the seated position.
7.Replace the ignition cable shoe.

A blown fuse is indicated by a burnt connector. Pull |
|
| |
the fuse from the holder when replacing. |
|
The fuse is there to protect the electrical system. If it |
|
blows again shortly after replacement, it is due to a |
|
short circuit, which must be fixed before the machine |
|
can be put into operation again. |
