When the engine starts, first allow it to operate in
short runs at the very rich starting settings, with
the glowplug battery still connected and the driving
wheels clear of the ground. The rich mixture will,
under these conditions, provide adequate
lubrication and cooling, indicated by profuse
smoke from the exhaust.
It is vitally important to set the
throttle at the correct position
before attempting to start the
engine. If the engine is allowed to
run with the throttle too far open
under "no load" conditions, it will
rapidly overheat and may be
seriously damaged.
Remember!
RPM High RPM Low Throttle Stop Screw
Throttle Stop Screw
If the RPM are lowered too much, the engine
stops. Set the idling RPM a little higher when the
engine is new.
Next adjust idling (low engine RPM)
Idling means …
Engine is started but the car does not move when the
throttle is positioned neutral.
Disconnect the glowplug battery If the car starts
moving (or tiers rotate), adjust the throttle stop
screw so that tiers may not rotate with steady
idling.
