Your Kohler should have the points on the same side as the carb, under a bubble-shaped cover that is held on with 2 screws, located toward the power end of the crankshaft and down in the lower corner of that side of the engine. A wire leading from the points goes to the - terminal of the coil. The condenser also connects to the - terminal of the coil. The wire coming from your ignition switch connects to the + side of the coil. The spark plug wire comes from the center tower of the coil. To test current at the coil, get a volt-ohm meter, set it at 12 VDC, and with the ignition switch ON, touch the black lead to the frame or engine and the red lead to the + terminal of the coil. You should get a reading. If not, then bad wires or ignition switch. Now, touch the red lead to the - terminal. You should get a reading. If no reading, remove the condenser wire and test again. If you get a reading then, coil primary is then good. Condenser is shorted out. Check the plug wire by setting the VOM to ohms and touching the leads to each end. Should get a full reading. Check the wire to the points from the coil by rotating the engine til points are open, then touching the red lead to the points terminal and the black lead to ground with ignition switch ON. Should get a reading. Test the points by removing the wire from the terminal, rotating engine til they close, then setting VOM on ohms. Touch black lead to ground, red lead to the point wire terminals. Should get a full reading (infinity, needle all the way over to spot where it would be if you touched leads together). It takes about 5 minutes to do these tests, can save a lot of time spent just guessing. Usually no spark is bad points...burned, oily or somehow not making contact.
