Spark plug
The spark plug condition is influenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type 
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug 
electrodes, which may result in operating problems and 
starting difficulties.
If the machine is low on power, difficult to start or runs 
poorly at idle speed: always check the spark plug first 
before taking any further action. If...

”Air Injection” centrifugal 
cleaning
Centrifugal cleaning means the following: All air to the 
carburettor passes through the starter. Dirt and dust is 
centrifuged out by the cooling fan.
IMPORTANT! In order to maintain operation of the 
centrifugal cleaning system it must be regularly 
maintained. Clean the air intake to the starter, the fins on 
the flywheel, the space around the flywheel, inlet pipe and 
carburettor compartment.
