QuickFuel 880 Surging/Missing At Wide Open Throttle

I went back to the leaner 84's in the secondary and kept the 80's in the primary side. I went for a ride and it really cleaned up on the top end but still surging from part throttle to WOT. I came back home and being by myself, I screwed the idle screw in to walk the idle up to 2000 rpm, put the timing light on and got 38 degrees. I then went to about 3400 rpm and got 44 degrees. I shut it down after that as I really didn't want to have it screaming any longer, any higher, to see where it would drop off. Being that high though, doesn't it mean that there is likely too much advance? I popped the hose off the vacuum canister on the MP distributor and used the 3/32 allan wrench to turn the vacuum advance to the right 1/2 turn to lessen the advance. I then used the vac gauge to recheck the idle mixture screws in all four corners, bringing them each in until noticing the needle drop a bit then backing out until the gauge reading was at its highest on all 4 corners. One thing I have been noticing is that the vac guage reading flutters between 11 and 10 in-HG. Everything I read indicates bad plug, bad wire, or plugs not gapped enough but I gapped them all at 35 and am pretty confident that the plugs and wires are all good. I didn't get a chance to take it out the other night to see if my vacuum advance adjustment made any difference (Page 5, #8 http://www.dippy.org/upgrade/ignition.pdf), but before I do, i'll also check for the .008" air gap, and then post my results tomorrow. Thanks.
