As long as oil pressure is good, no KR, a/f ratio good, do it. But I think you said it was kind of lean, it needs to be 12.8 at wot.
Around 75% throttle it starts to go richer, drops to the 13's. I haven't given WOT yet, just part throttle pulls. I hadn't given it that much throttle when we talked last.
Haven't seen it go richer than that, but that could be because I haven't opened it up.
