Holley 1920 Metering Blocks?

If you wouldnt mind posting them that would be great. I really appreciate all the help. So if I dont have the screw, I have to solder the idle air bleed and resize it to about .035? I'm not sure where it is on my Holley since theres no screw. Would you mind posting a pic? I know theres a small hole near the bottom edge of the float bowl sort of near the accel pump. But I'm not certain thats what I'm looking for.

Also, under heavy throttle it seems to gain and lose power like when you're running out of gas. Is this a lean out caused by the air bleed, that only goes away with the 64 jet because its so rich?

ok here is the screw (if you have it, it can be covered by lead)

now this pic is the idle bleed (Head Side). yours could be completely leaded over, small, or to large. if you have to drill it out you need to break down the carb and pull the idle mix screw out and blow the crap out of it.
