The throttle cable recently snapped on my Scag and I had to simply pull the throttle lever near the engine all the way to where the Kawasaki factory set-screw was set. The mower is raging with power now, goes about 2mph faster, with tons of cutting power. I don't have an RPM gauge..... is this throttle stunt going to damage my mower? Or am I now merely running it at the full 18 HP it was designed for? Thanks for your help.
