Snapping sound under load.

[Mitch//pa]

I've learned to sit back on these things, as i hate to jump to conclusions. Just about everytime I / WE never receive all the info needed to come up with a logical response other than an arm chair guess. Usually more info squeaks out as the threads progress. I / WE have learned on post #8 that the engine is quote running very rich. No matter what the end result is, or what the source of the snapping sound is the cause of this condition needs to be corrected.
