• If two adjacent cylinders have respectively low compression pressure and their compression remains low
even after the addition of engine oil, the head gasket is leaking. In such a case, replace the cylinder head
gasket.
8. Install spark plug, ignition co il and harness connectors. Refer to EM-16, "Removal and Installation"

1. Install a new O-ring on the electric throttle control actuator. CAUTION:
Do not reuse electric throttl e control actuator O-ring.
2. Tighten the bolts of electric th rottle control actuator equally and
diagonally in several steps in numerical order as shown.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
2. Start the engine and rev it up and check for fuel leaks at connections.
WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
