Question
my throttle runs wide open and I have pretty much came to the conclusion it has to be internal. I have adjusted the governor arm and cleaned the carb multiple times and the same thing persists. What does right look like in one of these engines? is there a way to check to see if it is bad before I go in? thanks in advance!

Answer
How did you adjust the governor arm?  Did you see this video on You Tube?

You will have to split the engine to replace any of the internal governor parts.

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.
