So I have an 88 Monte Carlo LS with the stock 305, but I recently removed the computer and swapped in a 600 CFM Holley 4160 list #1850 and an Accel red top vacuum advance distributor (I also wired up the torque converter lockup, but that's not relevant to my problem. I have adjusted the air/fuel mixture screws and the accelerator pump along with the distributor and the vacuum advance as best as I can, but the car still bogs and tries to stall if you give it more that slight throttle from a complete stop, but once you hit about 1300 RPM, you can floor it and it runs fine. In park the car is idling at roughly 1400-2000 RPM and in drive it is 800-1200 RPM, but the idle adjustment screw is all the way out. The electric choke is not currently hooked up, since when it is whenever you rev the engine the idle shoots way up to like above 3000 RPM. Does anyone know how I can fix these problems? The carb was brand new rebuilt before I bought it with 66 jets, a 9 plate, a plain secondary spring, and 6.5 power valve.
