25hp kohler hot start problem. Replaced fuel filter, plugs and cleaned air filter - same problem. it won'd restart when hot.

3 possibles come to mind
fuel vaporization in the line to the carby or in the carby bowl (check float level adjustment)
valves are being held open when hot--- valve stem lengths increase reducing tappet clearance___adjust valves when hot
check coil/ ignition module for failure when hot as they can open circuit ./ short circuit when internal components fail from heat

Why is motor not running now?

It sounds like you made a bad valve adjustment and it has thrown a rod, and binding on one cylinder, hence partial turnover, cylinder on compression. Pull apart again and re-check.

Hello, I need to know how to adjust engine timing for Kohler Command, 22hp engine, manufactered in 2007 on a Cub Cadet 2544 Heavy Duty tractor. Thanx, Rick

If you have what i think you have. The only timing adjustment as such would be in the coil to magnet air gas. Which is usually around .125 thou.

The other timing is done internally, when you line up the marks on the cam gear with the marks on the crank gear. good luck and be careful

Kohler motor starts then carb loads up with gas

If the engine is running rough then this could mean that you have weak spark or valve adjustment. When an engine runs rough it will not burn all the fuel, which will create excess fuel in the air cleaner housing. Also, make sure the the float is closing in the carberator.
