AVS2 carb tuning. Anyone with experience out there?

Going to bring this up to the top because I have learned some more and have changed some things. I have drilled the nozzle out, but can’t remember how big. If you search there is a recommended drill size. I have also found that in order to get the link in the arm I was pushing it up and loosing a bit of pump shot. Adjusted the link by bending it, so just as the plunger starts to resist the link freely goes in the hole. That helped a good bit with the lean spike at the hit. Going to play with fuel pressure now. I am running a Holley red with a big mechanical. No issues, but want to be able to bump the pressure up a bit to try and move more raw fuel. Going to log fuel pressure with how it is now, then go with Holley black pump and no mechanical.
