My left side igintion on my Kohler CV 20 just stopped. No Spark. Plug is good but no iginition on that side. I'm going to replace the ignition module on that side - but thought I would ask you guys if there is anything else that I should check as well. Thanks in advance - raining like crazy for the last few days, grass is growing like mad and I really need this machine (with 2 working cylinders!).
