I posted the specs from the manual and posted what I got when I tested it. The format changed when the post actually showed up though-I don't know why. It's a little harder to read but all of the info is there.

I'm hoping Roger Brown chimes in... I don't want to buy another AFM if I don't need to.

As far as carbon build up, I can't imagine there is any. The motor only has 10,000 miles on it. At this point, it doesn't really matter much what gas I put in-it pings like crazy anyway.

Timing is spot on.

I opened up the AFM and started fooling around with the mixture. I'll drive it a bit tomorrow and see if it makes any difference.
