That's exactly what I just finished messing with this weekend on my 67 Buick Riviera. That's a 4150 Holley. 650cfm vacuum secondary with an electric choke. Set your float height like others have said. Just search 4150 holley float height adjustment and you'll find a nice video on youtube form holley explaining exactly how to set it. Then do the same with the idle mixture screws. Then do the same with idle and high idle set screw setting. I would probably do all of that after getting a rebuild kit and rebuilding the carb. They are easy to rebuild.Update, I drove the truck around the yard a little today it fires right up idles fine doesn’t like taking off(accelerator pump?) and it seems to flood out in lower rpm times like I was backing up to the shed and it flooded out and stalled it started back up but stumbled and was smoking I put it in drive took off and it cleared up and ran fine. Could idle mix be the issue with the low rpm flooding? You can tell when it’s starting the issue because it acts like it’s got a cam with huge valve overlap and the accelerator pump issue worsens.
