Out mowing a few weeks ago & my Kohler K341 powered Walker just died. Cleaned the carburetor, took apart the fuel pump, cleaned out the fuel tank.....not a fuel issue. Bright blue spark, but it would fire & run until it got a little warm, then fail. Bought a new (NOS) ignition module from an old Kohler dealer locally. Ahh, this'll be a breeze. Sure, just like every mechanical task. Would have been easier just to pull the motor in the first place, but I tried to get the flywheel shroud off in frame, and it wasn't going to happen. Pulled the motor, folded a dollar bill for a shim, and got back in business in time to buzz through about an acre of grass. So much for a leisurely Saturday.
