1.Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission
Therefore, they should be periodically with new
ones.

6. IGNITION CABLES (Replace)
The ignition cables should. be replaced periodicall y with new
ones. After replacing, make sure that the ignition cables are
routed properly and fully seated.
NOTE
When disconnecting an ignition cable; be sure to ho ld the
cable boot. If the cable is disconnected by pulling on the
cable alone, an open circuit might result.
7. TIMING BELT (Replace)

Replace the belt with a new one periodically to ass ure proper
engine performance.
For disassembly and assembly procedures; Refer to GROUP
