Need carb and/or timing help

Checked the flow from the fuel pump while it was off...seemed strong enough....
You need a gauge.
Stumble off idle- are the throttle plates showing more than .040 of transfer slot at bottom? you may be not using the idle circuit.
Pull it and turn it upside down and check. If your curb stop idle shows more than .040; you need to drill holes in the front primary plates. Start at 1/16"

Alright.....I figured I have tried everything else, so would try this.

I took the carb off the car, took the top off, drained it....my transfer slots are like 4 x .040 or maybe more.........LOL....so they are very much exposed.

So I decided to drill it.

.......... removed , drilled and reinstalled the plates...1/16".

Got her all back together.

But, too late to let her run and test.....kids asleep upstairs, etc.....so just made sure she would start (she finally did once the carb got some gas).......couldnt tell much from the 30 seconds I let her run.

How much improvement should see? Or do I keep going up in size til it does make a diff?
