I have a huskee 21 hp briggs and stratton that ran fine the day before and then I changed oil in it and tried to crank it and nothing happened. I bought a new interstate battery and new post connections and still nothing. I turn the key and get no sound what-so-ever. You would think the solinoid would click but I don't even get that. Can someone help me out here some or just tell me what to look for. Thank you.

One thing comes to mind quickly, and yes it happens, did you hook the battery up wrong? Or, check the fuse, and safety switches.

Went to town and bought a new solonoid and new plugs. She turned over and runs fine now. Thank you for your response.
