I just bought a Toro proline 32" w/b and used it for the first time today. When I fired it up and started to cut with it it seamed like the engine wasn't at full power. The throttle was on high but in clumped up in some thick wet stuff. It has a 13hp Kohler on it. Is there a break in period for these or a governor that I can removed. I'll take it to the dealer if I can't figure it out myself.
