15. As applicable, install electric shutoff assembly,
ground and power supply wire.
16. Add minimum of one pint of engine oil to governor
through the upper governor housing plug (Figure 25).
Because injection plug is splash lubricated, engine
oil must be added to a replacement pump.

Adjust throttle cable or linkage so tang in outer
control lever is in "override position." At "override"
lever tang will be approximately half way from center
