4. Engine Servicing

- troubleshooting

Difficult Starting

Stop/start lever in the wrong position.

Decompressor lever in the wrong
position.

Incorrect type of fuel or oil.

No fuel in the tank.

Choked fuel filter or air cleaner.

Air lock in the fuel system.

Incorrect decompressor clearance.

Battery not serviceable.

Loose electrical connection.

Load not disconnected.

Turning the crankshaft the wrong way.

Method of Troubleshooting

1. Diagnose the problem by eliminating

the easiest things first.

2. Before starting to remove or dismantle

any components double check your
observations.

3. When electrical troubleshooting

always start at the battery first.

Exhaust Smoke

White smoke - generally as a result of
water in the fuel.

Faint blue smoke - appears with light
load.
Heavy blue smoke - caused by
lubricating oil passing the piston rings
due to stuck, worn or broken rings or a

worn cylinder.

Black smoke due to incomplete
combustion of the fuel can be caused
by overload, choked air filter, inlet air

temperature too high or incorrect

specification of fuel.

Overheating

Air inlet obstructed.

Overload

Lubricating oil level too low.

Hunting

Air in the fuel system.

Engine Stops

Lack of fuel.

Air in the fuel system.

Choked fuel filter.

Excessive overload.

Overheating.

Loss of compression.

Loss of oil.

Loss of Power

Incorrect tappet clearance.

Choked air cleaner or fuel filter.

Choked exhaust system.

Failure to Attain Normal Speed

Engine started on overload.

Fuel system not correctly primed.

Insufficient fuel.

Knocking

Loose coupling or pulley.

Engine loose on its mounting.

Incorrect specification of fuel.
