Mike pulled the AF cover and the filter was just as blocked as a 460 would have been after that much time. They didn't "fix" the air filtration issue at all in my opinion. Seeing that was a disappointment. In that area the 441 does better......
and the 372 better still by a long shot.
I leaned the 660 out to 13,800 after Mike left and to started running a lot stronger........I keep em pretty fat for the first tank at least. Hell of it was that the first big block I noodled with it was full of dirt in the center......took the edge off the chain right then.
We had a blast.......I'm tired though.
