446 Advice New To the Site

A little advice is needed on this 446 I recently aquired. Onan B43m 16 hp. It apears to me to have an oil leak at the area where the exhaust pipe connects to the muffler on the right side. It runs great and does not smoke. Under load it performs like it should. It liiteraly looks like oil dripping from muffler!! So i did a compresion test and found the right side to be at 89 and left side to be at 95 all within factory specs. Again it runs like a top and does not smoke except for a touch when started cold.
Advice???

I essentially have the same motor. Could it be that you have spilled oil around that vicinity adding a bit or when adding oil aftter an oil change?
