Piston wash is a new concept to me that I just read about.

Any motor that has been ran rich that I have seen (according to plug chop and general running characteristics) has had a ton of carbon build up on it. With the piston wash theory, that would make it lean.

I still need more convincing on piston wash.

Its back together now with less compression. The general conception is that the motor was lean. He went out on the jetting so we will see tomorrow.
