Horse power on 735cc engines?

What magic is Kohler using to get different hp ratings on the same engine? Or….is it a Cub Cadet trickeration?
 
Probably a different jetted carb, as manufacturers can only advertise engine hp as appropriate. Today’s engines are designated by cylinder size. Changing jet size will change horse power.
 
My 651V Kawasaki is rated @ 21.5 Hp, & with carb tweak, it can become 691V @ 23 hp, & again tweaked further, it becomes the 730V @ 24 hp, same bore & stroke. And all 726cc. So mine is living easy imo.

  • Displacement​

    726 cc (44.3 cu. in.)

  • Bore x Stroke​

    3.1 x 3.0 in. (78 x 76mm)

Kohler did the same thing with the CH18-20-22 engines. The 18 had a screw next to the throttle butterfly lever that limited it to only opening halfway. the 20 had the screw removed which allowed full throttle plate movement, and then the 22 added spark advance smart spark.

I wouldn’t have denied warranty if that screw were missing.

You wouldn't had to make that decision. The Kohler distributor rep that had to sign off on the replacement short block or engine replacement would of had the final say.

As long as there wasn't an engine failure requirement a short block or engine you would of been safe though.
 
As a dealer no but as a rep I would. Paul and a lot of reps might not even know that screw was there. Typically, they would call me, before I retired, or one of my associates before signing off or denying a warranty. But all reps are different.
