Thanks Ron. It's hard to tell if this one is rich or lean, but most are rich when the leaks are sealed.
21:1 sounds good, too. I've never had a problem with an oily or black plug since I got the carb tuned properly, even when I was running 16:1.
The extra-high fuel consumption is another indication that the main jet is possibly too large, causing a rich WOT mixture. (Still, that could just be due to a rich mid-throttle needle setting.)
