AVS2 carb tuning. Anyone with experience out there?

Hi there. A lot of great answers here. But you could also check this. The last new avs carb. I tuned the Metering rods were sticking in the bores. I polished them up and they moved nicely. But it still was running lean I had to fatten it a lot more than usual. Never went any farther as why but it ran good after.
