Wideband AFR tuning help.

I think I am rich with the 3310 with the secondaries also rich running 10-11
under throttle, and the 670 is lean running over 17 at cruise and also around
11 at throttle. I think the 670 is easier to tune with the jets having secondaries
also.

I think I am still in a bit of a crap shoot until I get my timing set up right.

The AFR sure has helped so far though showing my stumble off idle as way
lean. Changed the acc pump cam and it sure woke things up.

Isn't 16 a little lean for cruising at?
