Running 68 jets with the lightest spring puts me in the 14.5:1 range, it movs around a lot, but cruise is pretty close to that.
I put in 66 jets and cruise went to 17:1 way too lean.
It was ay 18+:1 at idle and would bog terribly, I didn't adjust the idle mixture, but the cruise was still too lean.
So it looks like I need 67 jets.
Now I've always been told you cant tell the difference between jets less than 2 sizes apart, but that was pre wideband days.
So I think I'll buy a couple of sets of 66, 67 and 68 jets in cace the flow variations are different enough within a jet size
The other idea is to drill the 68's a little.
Anyone have experience drilling jets?
