Stihl FS 300

Ignition timing is not adjustable.
Since there is no mechanical wear
in these systems, ignition timing
cannot get out of adjustment. How-
ever, an internal fault in the circuit
can alter the switching point in
such a way that a spark test will
still show the system to be in order
although timing is outside the
permissible tolerance. This will
impair engine starting and running
behavior.
