FUEL TANK

FUEL TANK REMOVAL

1. Drain fuel from tank.
2. With engine removed, loosen the two Torx™ screws (A)
securing fuel tank to chassis.
3. Remove fuel tank (B) by sliding filler neck through top hole
first, and sliding tank out front of seat assembly.

FUEL TANK INSTALLATION

TROUBLE SHOOTING

FUEL SYSTEM

1. Carburetor not choked sufficiently when engine is cold.
2. Water, dust, or gum in gasoline interfering with fuel flow
to carburetor.
3. Inferior grade gasoline or poor quality gasoline not
vaporized enough to produce correct fuel/air mixture.
4. Carburetor needle valve held open by dirt or gum. This
trouble can be detected as fuel flows out of the carburetor
when engine is idling.
5. If carburetor overflows, excessive fuel runs into the
cylinder when starting the engine, making the fuel/air
mixture too rich to burn. If this happens, remove the spark
plug and pull the recoil a few turns to let the rich fuel/air
mixture dissipate through the spark plug hole. Keep the
choke open during this operation. Dry the spark plug
thoroughly, screw it in to place, torque to specification, and
try to start again.

IGNITION SYSTEM

1. Wires of the ignition coil and/or spark plug disconnected.
2. Ignition coil damaged or shorted.
3. Spark plug cable wet or soaked with oil.
4. Spark plug dirty or wet.
5. Spark plug electrode gap incorrect.
6. Spark plug electrode is connected or bridged.
7. Incorrect spark timing.

COMPRESSION SYSTEM

If starting difficulties and loss of power are not due to the fuel
or ignition system, the following must be checked for possible
lack of compression.
1. Cylinder walls are dry and free of oil due to a period of
long storage.
2. Loose or broken spark plug. This causes a hissing sound
made by mixture gas escaping from cylinder in
compression stroke during cranking.
3. Damaged head gasket or loose cylinder head. A similar
hissing sound is produced during compression stroke.
4. Incorrect valve clearance:
If the correct compression is not obtained even after remedying
the above, disassemble the engine and check further as follows:
a) Valve stuck open due to carbon or gum on the valve stem.
b) If piston rings are stuck on piston, remove piston and
connecting rod from engine. Clean or replace parts.
