TROUBLESHOOTING

Engine Troubleshooting

Problem

Probable Cause Solution

Engine turns but fails

to start

Faulty ignition

• Install new spark plug(s). If engine

still fails to start, check for spark. If

there's no spark, SEE YOUR

DEALER.

No fuel to engine

• Make sure the fuel tank contains

fuel.

• Ice may be in the fuel line, filter or

pump. Add isopropyl alcohol to the

fuel system.

Poor engine com-

pression

• Mixture is too lean. A main jet that

is too small will cause seizure result-

ing in loss of power. This indicates a

major engine problem that must be

repaired before operating. SEE

YOUR DEALER.

Engine lacks power

Fouled or defective

spark plug(s)

• Replace the plug(s).

Fuel filter (loss of

high RPM power)

• SEE YOUR DEALER.

Incorrect clutching

• SEE YOUR DEALER.

Engine continually

backfires

Faulty plug(s)

• Change plug(s).

Fuel System

• Dirt or ice may be in the fuel system

(deicer should be added to non-etha-

nol fuel at all times for assurance

against fuel line icing).

Incorrect throttle

freeplay or faulty

switch

• SEE YOUR DEALER.

Engine requires

more than normal

pulls to start

Poor fuel

• Replace with fresh winter fuel.

Not enough fuel get-

ting to engine

• SEE YOUR DEALER.

Engine backfires but

fails to start

Spark plug wires

may be on wrong

cylinder

• Reinstall spark plug wires to the cor-

responding cylinder.
