Hey yall I'm back lol. So, today I went to mow the yard and when I checked the oil it looked excessively dirty, which got me curious because it's fresh oil (only a week or two old) So, I drained some into a container and sure enough it's murky, emulsified with gasoline and there's aluminum shavings floating in the oil. I grabbed my compression tester, hooked it up and got a reading of 50 PSI. The lawn mower shop gave me a ballpark compression of 70 pounds. Anybody have a more exact answer as to what the compression should be? It's a 140CC Briggs 550E series, model number 9P 702 0004 F1.
