Pre-mix with injection.
I finally got around to pulling the plug mentioned in post #57. It's dark, almost black, but dry with no hint of spooge. With stock jetting it was running a nice deep tan color. So, not too bad IMHO. Think I'll keep adding the extra oil for the cold weather months. Just for the feel good insurance I guess. On a side note, I,ve discovered another good reason to keep an old 2-smoker around, It makes a good waste oil burner.
