Kohler Command 22 HP surges and dies

This engine will start right up cold, run for about two minutes, then surge a couple times and die. I completely cleaned the carb, replaced all the fuel lines, and put new gas in it. I'm thinking the needle valve may be sticking, causing the fuel pump not to pump. Could this be the case? Once it dies, it will not restart... Any help is appreciated. Thanks.

Carb has auto choke and fuel shut off solenoid. Check both for working properly. Im betting the auto choke.

The solenoid was gunked shut, I cleaned it out and now it's working properly. Until I did that the engine wouldn't run at all. Now it runs for two minutes. The dashboard has a manual choke on it, would the carb still have an auto choke?

Put 12 volts to the solenoid and see how long it stays open.

I've got to get a new battery for this thing then I'll test it. I do believe we have a fuel starvation problem here. Whether it's the fuel solenoid, needle sticking closed, or fuel pump. I think you may be onto something with the fuel solenoid...

Boy do I feel like an idiot! First off, I appreciate the help guys. Turns out this was just a bonehead mistake by me. The other day I replaced all the fuel lines on this mower. Turns out, the one behind the air filter cover I had routed incorrectly, and it was getting pinched between the fuel solenoid and the air cover plate, hence restricting fuel flow. I have attached pictures of both the way I had it, and the correct way. It should go behind the fuel solenoid, not in front. Now this engine runs like a dream. :thumbsup:

So, it turns out it was the fuel solenoid causing the problem, just not in a way we all would have guessed! :laughing:

You were on the correct path thinking fuel starvation.:laughing::laughing:

This engine has 476 hours on it and it still looks and runs like a new one. What is considered 'high mileage' on these engines?

I have a courage 22 Model SV715 doing the same thing. Solenoid works fine just put a new fuel pump on it. Have new fuel line from pump to Carb. Carb has been removed and cleaned throughly. Still doing the same thing it was before I started. But only runs for 10-20 seconds. Have also put new spark plugs on it as well.

I am lost for answers.

A carburetor rebuild kit should get you going. Fresh gas, check air filter, take your time cleaning carburetor, after disassembling carburetor clean all orifices thoroughly before reassembly. Make sure you have all information, numbers, from mower manufacturer & engine numbers as many are listed.
