I'm just a homeowner - need help. I have a Kohler 18 hp Magnum Model # M18QS. I had been cutting the grass and turned the engine off. I couldn't re-start the engine. No clicking - no nothing. Battery is okay, I have rewired the entire system, new battery cables, solenoid and ignition. I have not replaced the starter - My reason is I have never replaced a starter - don't know where its located on the engine and don't know if it is difficult to change for someone with limited mechanical abilities.
