I don't recall right off what the recommended range of compression is for a 15hp Briggs, but 120lbs is certainly sufficient to start and run th engine. If its a 4 stroke it will be around 10.0:1 10-28-08 Right-o, 120 is great. Briggs no longer releases comp ranges, but states a minimum of 60 to run. Depending on model, that's probably a 7:1 or 7.5:1 engine. Briggs are designed w/low comp ratios for durability, resistance to detonation, and low fuel-grade requirements.

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.

When does an engine need to be rebuilt?
The easiest answer is when it fails a compression test. Buy a compression tester (farily cheap), and test each cylinder. If one single cylinder is below 120 psi, or if one cylinder reads 15% less pressure than the cylinder with the highest pressure, your engine should be torn down and checked. The problem might only be in the heads, but it's still time for some serious work.
