Thanks. It ran like a champ this weekend (10min B main, plus a bump to the 20min A), but 5 min left me a little less than 1/2 tank.
I'll give the 7.0 and a fresh plug a try. I need to spend a little more time on my idle, as it was only stable for 15-20 seconds, but so far, so good. This thing is going to scream.
