C. Pull out the delivery valve (IN), and reinstall the
spring and delivery valve holder.
-i
Piston Position in relation to the crankshaft angle (BTDC)
NOTE: When re-assembling the delivery holder,
adjust the location of the delivery valve (OUT)
to correct position using a wire.
D. Move the governor control lever to "Maximum
Fuel" position, and send fuel with the No 1
piston at around 'X' degrees BTDC in its
compression stroke. At this time, fuel flows from
the delivery holder.

E. Then slowly turn the crankshaft clockwise until flowing
fuel from delivery holder is stopped. Check the piston
position at this point. If the position is later than 'Y'
BTDC, use thinner shim. If the position exceeds 'Z'
BTDC, use thicker shim.
