Did some testing this morning... As usual Dom is spot on (and madscientist too). I did get the t-slot lean enough for low speed cruising with .028 IFR, .074 TSR and .082 IAB. Have the screws out 1.5 turns in front and 2 turns in the rear with a bit of secondary air added to maintain 1200, 8", 14.5 idle.

But I popped in .080 PMAB for a trial - sure enough it leans out a lot on the highway as the revs climb (still only on the primaries) but it's too rich as the mains come in. At this point I agree with madsc. that I don't know what on earth the people in that Innovate-hosted article were thinking!

And the damn thing STILL wants to cruise (15", 3000) at 12.5 to maybe 13 at best! Fuel curve looks like a roller coaster. Craptastic. Although driveability is still good except for a too-lean spot at low rpm on the slot.

So my next move will be to go smaller on the MAB, actually below .030. Also drop the PMJ's from #75 one or two sizes, and try it again.
