running, except where specified in the operator’s manual.
This gasoline engine has been carefully tested and inspected in our factory.
Generally, the machine will run normally without any adjustment.
After operating some time, it may be necessary to adjust the gasoline engine as
follows:
VALVE GAP
On the left side of the machine, remove the cylinder head cover, marked OHV
(

).
Check the valve gap with a feeler gauge (

).
If necessary, adjust the valve gaps:
intake valve (

) gap: 0.1 - 0.15 mm;
exhaust valve (
s, fig.13
) gap: 0.15 - 0.2 mm.
Grasp the valve gap adjusting nut (
