An old, original, Factory Technician Training Video I found - from the 1980's. I am uploading this video to Youtube to help anyone looking for answers and details about Ignition timing on older Tecumseh small engines. The video is long and dry - but walks through all of the correct steps necessary to correctly set the ignition timing on older Tecumseh and Lauson small engines made in the 1960's, 1970's and 1980's. Most videos on this topic on YouTube only discuss replacing the points and condensor. That usually works - but sometimes these older engines will be still be difficult to start, or have kickback problems. The Factory Trainer in this video explains in details why this procedure in important.
