Small Engines (Lawn Mowers, etc.)/How to drain gas from a Murray 8/30


I have my grandfathers Murray 8/30 rear engine riding lawn mower. It has a Tecumseh 10HP 30' deck. I'm trying to rebuild and get the mower back working as a tribute to him. Before I can do anything I need to drain the old gas out of the tank. I have no idea how to do this.
1) Can you please advise on how to drain the gas?
2) Do you know where I can find a manual on how to work on this type of mower/engine?

Any help would be appreciated.

To drain, dis-connect the fuel line from the carb or fuel tank and drain.

Remove the carburetor float bowel nut on the bottom of the carb to drain the carb.

Is this the manual for your engine?

I do not believe Murray made a service manual for the mower...I've never saw one.

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.
