Kohler cv16s Runs for 10 mins then dies

[watson]

Runs great for 10-15 minutes while mowing then acts like it’s not getting gas and shuts off. It does start again but does off after about 1 minute after that. Fuel lines are clear and flows from gas tank well. Probably going to replace the carb this weekend. Hoping there’s not an issue with the coil as well? Appreciate any and all input in advance! New to the small engine game but ready to learn!

Had Similar problem Valves were checked and adjusted works fine now good luck..

Sounds like the air vent in the fuel cap is not open.

No fuel or no spark, check both when hot. Open and close cap to check vent. Check spark.

Need to load test the ignition coil.

No one has mentioned the fuel filter.

I said fuel delivery issue.

Sounds like vapor lock, generally cured by replacing the gas cap. You can try cleaning it with soap and water, rinse the soap out and let it dry completely before trying again.

Test before buying a replacement. Can dry water with compressed air or WD-40.

Same issue as OP.
Chased the auto choke before finally pulling the float cap off. Little white crystals in the bottom , and build up on the large round tube? Don’t know the correct name.
In-line filter now and it runs good. Fingers crossed.

Check to make sure the float in the carb is level when held upside down. Sometimes the needle/seat swell and causes inadequate fuel flow to keep up with demand.
