Gurney Weslake 305 Problems

I have a '69 305 Gurney Weslake with 4 48 IDA's.

I can get it to idle fine but when I barely get into it it bogs and pops and cuts out and wants to die. I dont know much about these webers and i have heard many ways to smooth out the progression from idle to mains.

right now im sitting on 65 idle jets with 120 holders. I drilled out the original 70 idle jets to about .8 and it helped a lot but then went way too large and wouldnt run at all.

When I push past the hole it runs great all the way through 8k rpm so I know my mains are good.

I have heard about drilling the third progression hole but im not sure I want to do that just yet. I also heard about making the idle holders a bit larger. Any ideas?
