Stop the machine, apply the parking brake and switch off the engine.
Make sure that the compression lever is in position "0". See Starting
the machine.
Remove the cylinder head cover and gasket.
Turn the engine over in the normal direction of rotation until
compression is felt.
Check the inlet valve clearance between the rocker and valve stem
using a feeler gauge (a).
If the valve clearance is incorrect, loosen the hex nut (c).
Note: See Technical Data for valve clearances.
Turn the adjusting screw (b) with a screwdriver until feeler gauge (a)
can just be pulled through between the rocker and the valve stem with
slight resistance to its movement after nut (c) has been retightened.
Repeat adjustment with the outlet valve.
Place a new gasket under the cylinder head cover, replace the cylinder
head, and tighten down uniformly.
Run the engine briefly and make sure that the cover is not leaking.
