If engine does not start, push the
starting aid button while cranking the
engine, and hold for three seconds
(time required to fill the chamber).
Ether is injected when aid switch is
released. Use additional starting fluid
once every two seconds until engine
runs smoothly.
If oil pressure does not register within
first 15 seconds, stop engine
immediately and investigate. If oil
pressure is normal, proceed to step (4).
Low idling speeds during extremely cold temperatures can result in
incomplete combustion and heavy deposit formations on the valves.
These deposits can cause burned valves, bent pushrods, or other
damage to valve components.
Run engine at reduced speed only long
enough to circulate the oil through the
engine, then increase speed and warm
up the engine.
Cover the radiator if necessary to bring
engine up to operating temperature.
