Most Briggs and Stratton (B&S) engines of that size can have the spark plug gapped to 0.030" What I truly recommend is that you visit the Briggs and Stratton web site and download the engine owner's manual. You will need the Model Number, Type Number and maybe the Date Code. This information will be used to obtain the appropriate Owner's Manual. You can also obtain the IPL (Illustrated Parts List) for your particular engine. The web site is www.briggsandstratton.com - and you can take a look around for the manuals.
