Kohler 15.5 Command no change in idle
I have a problem with my Kohler Command 15.5 HP engine mounted to a Craftsman 46" riding mower.
The idle will not change no matter what the setting on the throttle.
Particulars: Family: SKH426VU1G2RB
The mower was running fine until I did the winter maintenance.
- Removed deck and power washed and cleaned all grass buildup
- Changed oil and filter
- Replaced Spark plug
- Replaced air filter
- Replaced fuel filter
I have removed the carb and cleaned it, removed the shut off solenoid and the shut off plunger is in the "up" position but will manually move up and down. I have removed the float from the carb and sprayed carb cleaner where I could, along with cleaning the entire carb. Both levers on the carb are moving freely.
The engine will start and run, but idle very low. Moving the throttle lever results in no change to the idle. Engaging the blades results in no change to the idle. After a few minutes the engine will "sputter" and act like it is out of fuel, but will continue running rough.
I removed the gas cap and blew out the fuel line (before replacing the fuel filter) and also had the engine running while I removed the gas cap, still no change in the idle speed.
Any suggestions as to where to start....???
