What can i do to my 12hp kohler engine (K301) to make it have more power/torque?

Question

This engine is currently in a Cub Cadet 125 hydro-stat rider mower. Its rated at 12hp but i need a little more horses working for me, or at least some more torque. How do i do this? any help is much appreciated.

Answer 1

There isn't much that you can do except keep it tuned up and maintained.  I guess that you could put a smaller pulley on the front or a larger pulley on the rear.  But that small engine will always be the same.  Why not go for a larger engine?  Bypassing the governor will lead to quick engine failure.

Answer 2

Unless you want to race the thing (yes, they do this) best to leave it alone.

If you feel the need to embrace the inner Tim Allen in you....

Maybe check and see if your throttle is opening all the way (check the cable adjustment.)

There might also be a governor you could bypass...
