My daughters mini bike with a 3hp Briggs has 80psi compression and runs great. A motor I got "running" off eBay has 55psi compression, runs but has NO power. -Jason
Briggs and Stratton does not release specific compression values. Anything above 120 psi should be just fine, around 90-100 and you're most likely due for a rebuild. A better test is a leakdown test, with can help in determining where compression is being lost.
Three specs are considered critical; the connecting rod cap at 110 in-lbs, the sump cover at 110 in-lbs and the cylinder head at 165 in-lbs.

The recommended plug gap for the 1993 model, 3hp Evinrude outboard is .030 in.
