Here is a Part2 of the Original Tecumseh Factory Training Video I found in my archives - from the (now out of business) original Tecumseh Engine Products Company. I am uploading this to Youtube for anyone who want to see what Service Technicians and Small Engine Shops used for Troubleshooting Tecumseh Engines. The video is old (from mid- 1980's). - but does provide some insight into troubleshooting Ignition systems on older Tecumseh small engines. The video also shows some special tools used for testing ignition components. Hopefully this video may help you to diagnose and fix common engine ignition problems.
