Mudsport96:
If i  remember you had DG rods in it. They are a bit richer than the DRs. Could always try them again

Zyen:
i dont have a 'nice' assortment;  DG, DR, DP and V, N, P, L.  currently running richest i have.

the problem i see currently is i *think* the mains arent tuned properly yet.  still working on that.
however, as this 4.3 will never open the 2nd door past ~40% and all the secondary rods are +/- 0.002" at that setting, i don't know how much difference that will make.

Mudsport96:
I would use the DP rods and tweak the hanger a little to lift them higher.

while i appreciate the advice, i don't see how going to a much leaner rod can fix a lean bog on the secondaries.   at 40% the DP is 0.1157" whereas the DG is 0.1075".  even bending the hangar to get the rod to 60%, the DP is still 0.100" fatter.
am i missing something?

Mudsport96:
My mistake. I was lookin at the specs for CP... not DP.    :o ill be over in the corner....
