I'm in Birmingham, AL. I'll check tomorrow about the rental of equipment.
Yeah, I had somebody cut open the last oil filter that came off and they said it was clean. There doesn't appear to be any loose metal in the oil. So at least nothing is coming off in pieces........
Is it possible that one of the valve springs is "loosening-up" once it warms up, or is that not possible? Also, does the fact that it doesn't make any noise under load OR deceleration give any clues to what it might be? The fact that it only does it under netural throttle or very light acceleration and in a fairly narrow rpm-range, should be suggestive of something I would think.
