Small Engines (Lawn Mowers, etc.)/Briggs magnetron coils

Question
I have 3 briggs armature magnetrons coils, all with differing air gaps at the top. Which type should I use to cause a delay in timing of briggs engine. (Why is there different enclosed air gaps on the armatures themselves?

Answer
Air will have a minimal, if any, effect on timing.

To really effect timing you have two options; mechanical and electronic.

Mechanical usually involves a different camshaft.  Electronic is controlled by the location of the coil or the flywheel.  You can purchase offset flywheel keys to advance or retard the timing by 5 or 10 degrees.

Why do you want to change the timing?

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
