    Briggs riding mower won't start
    Hello everyone. I need a little help with my briggs and stratton 12.5 hp riding mower. I haven't used it in a while and today I was trying to start it up, but to no success. Usually when this happens, its because my battery so I jumped the battery and it still did not work. All it does is make a click noise when I turn the key to start. So I went to Lowe's and bought a new battery and stuck it in and same result. I bought a new spark plug, but some new oil in, and even new gasoline. Still the same result. The mower just makes one click and nothing else. Occasionally after the single click when I turn the key, the engine would make a noise like its trying to crank up, but still nothing. I must tell you guys that I know NOTHING about mowers. I just know a couple of things about cars, but ABSOLUTELY nothing about mowers. I ruled out that it isn't the battery because I have a new battery and the thing in the engine that spins when it is suppose to try and start doesn't even spin. Please help me out guys. THANKS!

    With engine off. Turn the cover on the flywheel backwards about 1/4-1/2 turn and then try and start. Many times it hold compression if the valves are loose and the piston ends on the compression stroke.

    Sorry but like I said in my first paragrapg, I know NOTHING about mowers so I don't know what you speak of. Are you talking about the circle thing in the engine that spins?

    Check your battery cables, sounds like they are corroded and also see if you can turn the starter by hand

    I tried to turn the thing in the middle of the engine but its just impossible to twist by hand. Is the starter the key? I am really sorry for the dumb questions, I just know nothing about this stuff. Yes the batter cables are pretty rusted so that could be the problem and if it is, what should I do?

    Hook The Black Jumper Cable To The Mower Frame, Then On The Starter There Is A Connection Towards The Bottom Of It, Touch The Red Jumper Cable Here.
