High Speed (Rpm) Adjustment; Adjusting High Speed (Rpm); Choke Adjustment - Kohler Courage SV470-600 Service Manual

NOTE: Do not crank the engine continuously for
more than 10 seconds at a time. If the
engine does not start, allow a 60 second
cool down period between starting
attempts. Failure to follow these
guidelines can burn out the starter motor.
NOTE: If the engine develops sufficient speed to
disengage the starter but does not keep
running (a false start), engine rotation
must be allowed to come to a complete
stop before attempting to restart the
engine. If the starter is engaged while the
flywheel is rotating, the starter pinion and
flywheel ring gear may clash, resulting in
damage to the starter.
If the starter does not turn the engine over, shut the
starter off immediately. Do not make further attempts
to start the engine until the condition is corrected. Do
not jump start using another battery (refer to "Battery").
See your Kohler Engine Service Dealer for trouble
analysis.
3. For Operation – After the engine starts, move the
throttle/choke control from the "fast/choke on"
position and set the desired engine operating
speed (between the "slow" and "fast" position).

High Speed (RPM) Adjustment

The recommended maximum no-load high speed
(RPM) for most engines is 3300 RPM. The actual high
speed (RPM) depends on the application. Refer to the
equipment manufacturer's instructions for specific
information.
WARNING: Over speed is Hazardous!
Do not tamper with the governor setting. Over speed is
hazardous and could cause personal injury.
1. Make sure the throttle cable is adjusted properly
(see ''Throttle Cable Adjustment").
2. Start the engine and allow it to warm up. Place the
throttle control lever into the ''fast'' or high speed
position. Turn the choke adjustment screw (See
Figure 5-13) out/conterclockwise, so there is
clearance from the choke lever, and that contact
cannot occur during Step 4. See Figure 5-13.
3. Align the hole in the throttle lever with the hole in
the speed control bracket by inserting a pencil or
6.35 mm (1/4 in.) drill bit. See Figure 5-15.

4. Loosen the speed control bracket mounting
screws. Slide the bracket forward or backward,
until the desired high speed (RPM) is reached.
See Figure 5-17. Check the speed with a
tachometer.
Figure 5-17. Adjusting High Speed (RPM).
To increase the high speed (RPM), move the
bracket toward the carburetor.
To decrease the high speed (RPM), move the
bracket away from the carburetor.
5. Tighten the speed control bracket mounting
screws. Recheck the speed with a tachometer
and readjust if necessary.
Torque the mounting screws as follows:
Into new as-cast hole – 11.0 N·m (95 in. lb.).
Into used hole – 7.5 N·m (65 in. lb.).
6. Adjust the choke (see ''Choke Adjustment'' which
follows).

Choke Adjustment

This procedure must follow the "High Speed
Adjustment" just described. If not already completed,
perform that operation first.
1. Turn the choke adjusting screw out
(counterclockwise), until it no longer contacts the
choke lever. Then turn it back in (clockwise), until
it just makes contact.
