I've found that a lot of the newer engines have an elevated HP rating gained by higher having RPM's. Something we all will have to compensate for as engines need replaced.

If you look at the ratings on the Honda clones that are so popular you'll see the continuous rating isn't as impressive as the nominal HP rating. I had a look at the manual for a 13hp clone and the continuous rating was 9 hp. I think some of it comes down to displacement. A 14hp Kohler K321 is over 500 CC's while a 13hp clone is 390cc. Even a 15 hp clone is still a lot smaller then the older engine.
