Small Engines (Lawn Mowers, etc.): Kohler Pro 17-OHV wont start, hydraulic lifters, question pool

Question
Kohler Pro 17-OHV won’t start.
Engine was running fine when I shut it off. Next day, engine would not start, symptomatic with flooding.
Plug was soaked.
Changed plug and tested plenty of spark.
Engine spins and mis-fires but does not start.
Dismantled and cleaned carb, float etc. Plenty of fuel supply.
Same result of engine spinning & occasional back-fire but no start.


Answer
Hello Shane:

Sorry for the Delay. This Question was Located in the Question Pool and I can Only Answer Questions from the Question Pool when I am Not Answering Questions here or at the Other Site I Answer Questions at. It Sounds like the Flywheel Key is Damaged, the Valve Clearance Requires Setting (if this Unit has Tappets and Not Hydraulic Lifters or the Cam May have Twisted. Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. Thanks.
