Where did I say I ran it without mufflers and filters? Anyway, mufflers are in place and filters are on. But I did notice when filters were off that it did backfire more. And still, nobody comments about the oil. The clean oil on the right, but dirty out of the drain plug and left side. I'm sure oil pump is ok because there is oil pressure when running. Wierd huh?
