Pauley, Kohlers are not to be turned up too high on the gov/RPMs.....they are preset to run 3400-3600 RPMs, take some advice, don't mess with it.
BTW, I just got a new LTX 1046 this season, and I love it. It has the 22 HP Kohler, plenty fast & powerful.:biggrin:
Thanks for the info. I guess I'll just leave it where it's at.
