Arrived quickly but most of all was easy to find with the parts diagram
The parts diagram makes it easy to locate the part without knowing the actual part name. The price is competitive I know because I looked for the price on other sites

Engine ran fine with starter fluid but would not start, hot or cold, even after carb cleaning

Convinced the carb was still the issue despite cleaning attempts, and since I was replacing the carb, to bring the mover back to practically new specks (It was 4 years old), I replaced the carb, choke, and diaphragm. Fuel frequently evaporates around the gas cap, so I am also replacing the gas cap since ethanol fuel is such a problem nowadays
1. Removed the starter (71"Lbs)
2. Removed the engine housing
3. Clamped and disconnected the fuel line (Small amount of gas drained)
4. Removed the air filter housing and air filter
5. Removed the three carb retaining nuts (71"Lbs)
6. Unplugged the spark plug
7. Removed the auto choke retaining nuts (No torque specs, just moderately tight)
8. Removed the choke torx screws (2)
9. Removed the diaphragm torx screws (2)
10. Removed the vacuum lines going to the carb/air cleaner housing
11. Completely removed the air cleaner housing
12. Completely removed the choke assembly
13. Completely removed the diaphragm assembly
14. Removed all linkages, used a small pair of needle nose on the throttle spring
15. Removed the old carb and gaskets
16. Pulled the old gas cap out of the tank (The fingers are plastic and will bend with a small amount of force)
17. Swapping old parts with new parts, assemble by reversing disassembly steps. Ensure you put in the two new carb gaskets and torque everything as documented by Kohler
By about halfway through a starter pull, the engine was running. It had not started that fast since it was new, and ran like new once re-assembled. You can probably cut the expense by a third if you just replace the carburetor, but I wanted a like new machine starting over again for at least 4 years. Pay close attention to fuel stabilizers and emptying the tank at year end. These things gum way too quickly with modern fuels. I never did figure out what I missed cleaning the original carb

Choke was weak and allowed the linkage to vibrate loose. Replaced both and mower started first pull.
