go to B&S site they have all gap setting for every engine they have made.
0.030 is the gap for briggs and stratton 4.5 hp mower
The gap should be about .0125 in. (.3175 mm.) or the thickness of heavy paper.
The easiest way is to use a standard business card between the coil and the magnet part of the flywheel.
The gap should be between .006 and .010 if it has aluminum clylinders. The gap should be between .010 and .014 if it has cast iron cylinders.
