11. Check the speed control shaft performance and
check its springs. The inner spring is correctly set if
it rejects the push of the governor pin.
See
Figure 10-78.
12. The outer spring is correctly set when the
accelerator lever is held in position during a higher
engine speed rate.
Increase its tension by
changing the position on the ratchet plate. Also,
check its reaction in the opposite direction. See
Figure 10-79.

4. Put the cylinder on the bench with its upper side
touching the bench.
Note: Never tap on the piston crown.
Note: Never install the piston from the upper side of the
cylinder because the liner is narrower and lightly
tapered in this position.
5. Compress all of the rings with a ring compressor
tool and drive the piston in the cylinder.
