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

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.

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

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?

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

[Zyen]

LOL.
i understand...get cross-eyed at times looking at all these things.

rebuild kit came in yesterday for 'new' carb.  i wound up stripping couple air horn screws (which were very close to gone already), so gonna clean/install/tune new carb.  may very well be 'starting over', but this core is in much better shape than what's on there now.
gonna put it back how i received it with 71/41 and DG/P.
will update soon.

P is about the leanest hanger there is.
Most V6 marine Q-jets i have seen has an E-H secondary rods hanger (with DH secondary rods).
If you want richer use a B-H hanger with your DG rods.
