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 the spark plug is dirty, 
clean it and check that the electrode gap is 0,9-1,0 mm. 
The spark plug should be replaced after about a month in 
operation or earlier if necessary.
CAUTION!  Always use the recommended spark plug 
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a 
suppressor.
0,9 - 1,0 mm
