Low Compression on Briggs and Stratton Platinum

I've got a Briggs and Stratton Platinum Series engine on a Craftsman push mower. The mower is a trash pull, but it's nearly new. The compression was at 10 psi when I got the mower. The valves look okay, but I took them out and cleaned them to be sure. I didn't see oil leaking into the cylinder so I don't think it has bad rings. I have a new head gasket on order in case the old one was blown. If you have had a similar experience with one of these engines, I'd appreciate it if you could tell me what was wrong with yours.
