Possible Cause

Operation

Bear in mind that many problems engines have, derive from

the use of the wrong spark plug

Intake joint cracked or with a bad seal

Replace the intake joint and check its tightness on the crank-

case and on the carburettor

Purifier-carburettor fitting damaged

Replace

Excessive oil consumption/Exhaust smoke

EXCESSIVE OIL CONSUMPTION/SMOKEY EXHAUST

Possible Cause

Operation

Excess of encrustations in the combustion chamber

Remove the encrustations

Engine tends to cut-off at full throttle

ENGINE STOP FULL THROTTLE

Possible Cause

Operation

Maximum nozzle dirty - lean mixture

Wash the nozzle with solvent and dry with compressed air

Dirty carburettor

Wash the carburettor with solvent and dry with compressed air

Water in the carburettor

Empty the tank through the appropriate bleed nipple.

Air filter dirty

Clean or replace

Defective floating valve

Check the proper sliding of the float and the functioning of the

valve

Tank breather hole obstructed

Restore the proper tank aeration

Engine tends to cut-off at idle

ENGINE STOP IDLING

Possible Cause

Operation

Minimum nozzle dirty

Wash the nozzle with solvent and dry with compressed air

Starter that stays open

Check: electric wiring, circuit continuity, mechanical sliding and

power supply

Reed valve does not close

Check / replace the reed pack

Wrong idling adjustment

Correctly adjust the engine idling and check the level of the

C.O.

Spark plug defective or faulty

Replace the spark plug with one with the specified degree and

check the plug gap

Excessive exhaust noise

INCREASED NOISINESS

Possible Cause

Operation

Secondary metal air pipe deteriorated

Check the seal of the piping on the crankcase and on the hous-

ing, check the piping between the housing and the muffler.

Good condition of the missing secondary air circuit components

Check the individual components and the piping, check the

precision of the fitting. Replace the damaged components

High fuel consumption

HIGH FUEL CONSUMPTION

Possible Cause

Operation

Air filter blocked or dirty.

Clean according to the procedure
