Kohler 7000 Series Boletín de servicio
The potential exists for these engines to stall for no apparent reason. This issue is limited to KOHLER
7000 Series engines within the serial number range of 45327xxxxx through 4613302464. Not all engines in
this serial range will exhibit the condition.
If a customer experiences a stall condition, check the standard items such as proper fuel level, inspect for
fuel cap vent operation, as well as proper fuel flow to the carburetor. If all of these items are found to be
correct and the stall condition still occurs, it is recommended to perform the following fix that involves
cutting the existing evap line as shown in Figure 1, inserting a new T-Fitting (25 155 56-S) and a new line
(25 326 28-S 14" cut to an 8" length) that will connect to fitting on air cleaner base.
NOTE: Refer to the appropriate service manual
disassembly and reassembly procedures as
needed.
1. To access the evap line, remove the air cleaner
cover, air cleaner element, and air cleaner
base.
2. Locate the existing evap line (as shown in
Figure 1), remove it from the purge port
nipple on the carburetor, and cut it in half.

3. Install the new T-Fitting at the location of the
cut line. Take the new 25 326 28-S 14" long line
and cut it to an 8" length. Install and route the
new 8" long line as shown in Figure 2.
