Hey guys, what's up? I have a Kohler cv 12.5 and it has no spark. It was running and mowing within the last day. I tried another used coil, still no spark, Then I tried a third used coil, still no spark. When I put the used coils back on their original engines, they have spark. What gives? I disconnected the ground wire from the coil to eliminate all wiring problem possibilities. I also got a faint spark a couple of times. I would consider myself a decent mechanic, so I don't think I am overlooking anything, but why would an engine not have spark with a good coil. I even tried 2 different flywheels. The magnet on the flywheel is still magnetic, and I know I am cranking her at at least 55o rpm. Any thoughts?????????????
