Need tuning help on 340 (Part II)

Yeah, I think I'm not too far off. And my sense is that this is a way better carb than the 600 or 750. Both of which I've run.

Idle is good. But I get A/F readings of 14-14.5 in power now (part throttle acceleration) and I'd like it a bit richer. While my cruise is already fat at 12.5 and I definitely want that leaner.

My struggle is that I am already using the 75/37 rod to keep fuel in power mode, but keep cruise lean. 75 is their fattest rod, 37 their thinnest. So I can't get a leaner cruise without jetting down, and then my "power" is leaner.

It's possible that, as crackedback suggested, if I get my jetting closer to the 41% primary/59% secondary split in jetting of the stock carb, that some of this will work better?????
