Briggs and Stratton is an online store that sells lawn mower parts and the tools required to repair them. They sell just about everything related to lawn mowers and the prices are pretty low.
You may be able to find one at a lawn mower parts and repairs shop. Check the Yellow Pages for one near you.
The Briggs and Stratton part number for a standard spark plug is 496018S. You can either buy this exact plug or call around to local lawn mower shops or auto parts providers (NAPA, O'reilly's...) and get them to cross reference the part number to see what other plugs will work.
Customers can order Briggs replacement parts directly through the Briggs & Stratton website. Parts can also be ordered from retailers such as Sears and Lowe's.
You can get that info on the Briggs and Stratton website. Just go to: http://www.ereplacementparts.com/briggs-and-stratton-parts-c-16758.html?gclid=CPCZj4vGr58CFZdM5Qodp3bDsA and enter your engine model number.
Briggs & Stratton parts would be used on air-cooled gasoline engines. The company is the world's largest manufacturer of these engines which are mainly used for outdoor power equipment.
If you get the model and serial numbers off the engine, you can probably find the part at a local mower repair shop or at Sear's.
I recommend you go to your local Walmart Lawn and Garden Dept or automotive parts store or lawn mower shop. They have manuals that will specify the filters applicable to your engine.
