Idle setting too rich:
If engine is down on power, difficult to
start or runs poorly at idling speed, first
check the spark plug.
:
Turn low speed screw (L) clockwise
1
(about / turn) until the engine runs
:
Remove spark plug - see “Starting /
4
and accelerates smoothly.
Stopping the Engine“.
:
:
Clean dirty spark plug.
Check electrode gap (A) and
readjust if necessary – see
"Specifications".
:
Use only resistor type spark plugs
of the approved range.
Rectify problems which have caused
fouling of spark plug:
:
:
:
Too much oil in fuel mix.
Dirty air filter.
Unfavorable running conditions,
e.g. operating at part load.
Fit a new spark plug after approx. 100
operating hours
Wrong fuel mix (too much engine oil in
the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition of
the spark plug. These factors cause
deposits to form on the insulator nose
which may result in trouble in operation.
or earlier if the electrodes are badly
eroded.
