O.S. Engines FS-26S-CX - Manual (Page 21)

When cleaning the exterior of the engine,
use methanol or kerosene. Do not use
gasoline or any solvent that might damage
the silicone fuel tubing. ●
PARTS REPLACEMENT
Over a long period, depending on how well
your engine has been protected from the
ingress of dust and grit and other causes of
wear and tear, loss of performance may
eventually occur in the form of reduced
power, reluctant starting, unstable idling, etc.
Having checked that this is not due merely to
the need to readjust the valve clearances (for
which an O.S. Valve Adjustment Kit - Code
No. 72200060 - is available) inspection may
then reveal that the replacement of some
parts may be called for.
Contact the O.S. distributor in your country
for parts or full service. See pages 21 of this
booklet for details of parts. ●
