Speed Setting
MODEL SERIES 190000, 200000, 230000, 300000,
320000 (Cast Iron Cylinders)
For fixed speed operation, loosen lower stop nut. Adjust
top stop nut to obtain top no load governor R.P.M. as
shown in Engine Sales Manual, Note column. Tighten
lower stop nut. Fig. 24.
For remote control operation, adjust lower stop nut to
obtain top no load governed R.P.M. as specified in the
Engine Sales Manual, Note column. Fig. 24.
To adjust governor idle refer to Section 4, Governor
Controls and Carburetor Linkages.

OBTAINING CLOSER GOVERNING
(Generator Applications Only)
Governor regulation to within two cycles of either 60 or
50 cycles can be obtained if the following procedure is
done:
MODEL SERIES 100000, 130000
a.
1800 R.P.M., 60 cycle or 1500 R.P.M., 50 cycle
generators -- Push speed adjusting nut in and up to
release spring tension, Fig. 25. Start engine and pull
out on speed adjusting nut to the maximum length of
travel. Set engine speed to 2800 R.P.M. by bending
governor tang, Fig. 21. With engine still running,
return speed adjusting nut to slot and turn nut to
obtain 1875 R.P.M., 60 cycle, or 1600 R.P.M., 50
cycle, no load.
b.
3600 R.P.M., 60 cycle or 3000 R.P.M., 50 cycle
generators -- Push speed adjusting nut in and up to
release spring tension, Fig. 25. Start engine and pull
out on speed adjusting nut. Set engine speed to
4600 R.P.M. by bending governor tang, Fig. 21.
With engine still running, return speed adjusting nut
to slot and turn nut to obtain 3700 R.P.M., 60 cycle,
or 3100 R.P.M., 50 cycle, no load.
MODEL SERIES 140000, 170000, 190000, 220000,
250000 (Aluminum Cylinders)
a.
1800 R.P.M., 60 cycle or 1500 R.P.M., 50 cycle
generators -- Push speed adjusting nut in and up to
release spring tension, Fig. 25. Start engine and pull
out on speed adjusting nut. Set engine speed to
2600 R.P.M. by bending governor tang, Fig. 21.
With engine still running, return speed adjusting nut
to slot and turn nut to obtain 1875 R.P.M., 60 cycle
or 1600 R.P.M., 50 cycle, no load.
b.
3600 R.P.M., 60 cycle or 3000 R.P.M., 50 cycle
generators -- Push speed adjusting nut in and up to
release spring tension, Fig. 25. Start engine and pull
out on speed adjusting nut. Set engine speed to
4200 R.P.M. by bending governor tang, Fig. 21.
With engine still running, return speed adjusting nut
to slot and turn nut to obtain 3700 R.P.M., 60 cycle
or 3100 R.P.M., 50 cycle, no load.
