QUESTION: Hi Eric
Thank you for your reply there are no obviouse bit sticking in the engine from the out side that I can see but I will have another good look around and see but I can't move the pull cord. At all it's almost like some thing is stuck or ceased the problem is I lent it to a friend and that's how he returned it so I am not too sure what even caused the problem
Kind regards
Brian

Answer
With the spark plug out, and you can't move the cord, it does sound like it may be seized.

However, to be absolutely sure we always make sure there are no external parts preventing the engine from spinning before we start to look inside.

Can you turn the engine in either direction with the socket?

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.
