Dual Carb Setup Questions

[Archrms]

I have dual holley 1850 600cfm carbs on my 427 s/o. Been having some issues with stumble off idle, and gas dripping into intake after engine is shut down. Rebuilt both carbs and found some issues I was not aware of and want to either confirm whether they are correct or need to be fixed. I assume that both carbs should be set up identical to each other:

1. Main jets (both of mine were 65)
2. Accelerator Pump Discharge Nozzle (front was 35, rear was 31)
3. Accelerator Pump Cams are both the same profile and both set on #1 holes.

The front carb engages the accelerator pump almost immediately. The rear carb has a delay due to the progressive linkage. The rear pump does not seem to have as much movement on the pump lever as the front does - is this normal?

Never really paid much attention to the carb setup, as it worked fine up until now. How are yours set up in comparison to mine, and what needs to be changed/adjusted?

Thanks, Ron
