Starting an Engine Equipped with Unitized Throttle
and Choke Control

Cold Engine or Warm Engine
NOTE: Do not crank engine continuously for more than
10 seconds at a time. If engine does not start,
allow a 60 second cool down period between
starting attempts. Failure to follow these
guidelines can burn out starter motor.
NOTE: If engine develops suffi cient speed to disengage
starter but does not keep running (a false start),
engine rotation must be allowed to come to a
complete stop before attempting to restart
engine. If starter is engaged while fl ywheel is
rotating, starter pinion and fl ywheel ring gear
may clash, resulting in damage to starter.
If starter does not turn engine over, shut starter off
immediately. Do not make further attempts to start
engine until condition is corrected. Do not jump start
using another battery. See your Kohler authorized dealer
for trouble analysis.
1. For a Cold or Warm Engine – Place throttle/choke
control into fast/choke ON position. This will also
place choke into ON position.
2. Make sure equipment is in neutral.
3. Activate starter switch. Release switch as soon as
engine starts.
4. For Operation – After engine starts, move throttle/
choke control from fast/choke ON position and set
desired engine operating speed (between slow and
fast position).

Speed Control Bracket Mounting Screw
Recommended maximum no-load high speed (RPM)
for most engines is 3300 RPM. Actual high speed
(RPM) depends on application. Refer to equipment
manufacturer’s instructions for specifi c information.
NOTE: If engine is equipped with a fuel pump, carefully
remove fuel lines from housing and remove
pump from bracket.
1. Make sure throttle cable is adjusted properly (see
Throttle Cable Adjustment).
2. Start engine and allow it to warm up. Place throttle
control lever into fast or high speed position. Turn
governed idle adjusting screw out/counterclockwise,
so there is clearance from control lever, and that
contact cannot occur during Step 4.
3. Align hole in throttle lever with hole in speed control
bracket by inserting a pencil or 6.35 mm (1/4 in.) drill
bit.
4. Loosen speed control bracket mounting screws.
Slide bracket forward or backward, until desired high
speed (RPM) is reached. Check speed with a
tachometer.
To increase high speed (RPM), move bracket toward
carburetor.
To decrease high speed (RPM), move bracket away
from carburetor.
5. Tighten speed control bracket mounting screws.
Recheck speed with a tachometer and readjust if
necessary.
Torque mounting screws as follows:
Into new hole – 11.3 N·m (100 in. lb.).
Into used hole – 7.5 N·m (65 in. lb.).
6. Adjust governed idle (see Governed Idle Adjustment
which follows).
