Edelbrock Carburetor tuning question...

First thing I do with and eddy is check vacuum and put the correct step up springs in. Nothing else matters if it can't move rods at the right time
This is where I am. I have bigger squirters in my 600. I got them from a 750 that was junk and giving to me for free. I have the accelerator pump on the richest setting also. this has helped a lot, but I have ordered the step up springs for 12 bucks. This is my last attempt to cure, then I'm swapping to a Holley.
It's a shame that the whole classic car industry is trying to deal with this "bog" in the eddy's, yet eddy seems to have no knowledge or the will to do anything about it.
