Adjusting Float level>> http://www.holley.com/data/TechService/Technical/Carburetor%20Tech%20Info.pdf if you tighten the nut it raises the fuel level.
Unless your Carb is older than 1992 it will have a Check Valve that prevents the Power Valve from blowing during a backfire through the Carb.

Firing Order >> http://boxwrench.net/specs/chevy_sb.htm #1 on Cap can be positioned anywhere, align pointing towards #1 plug, make sure Vac cannister has room for adjustment.

Really dont think its the Carb to be honest. Car ran just fine when I had to take the intake off thinking it was a bad lifter when in reality it wound up being a intake bolt that was too long. My block was cast in 69. I didnt time it originally. Was told that all was done to time it last time was drop the dizzy in pointed at #1 (with #1 piston at TDC) and it ran just fine. Ive tried that and it didnt work for me. Used a degree wheel and a piston stop and did what was suggested. Ran it one way marked then ran it the other and marked used difference in the two and set it there. After that the car would idle and start fine but if you did anything other than gradually push the pedal it would spit back through the carb. So I think that led alot to think the carb might have issues but I still dont think that is it. The car idles but it still sounds like its missing to me like the timing is still off albeit very close. Its a real head scratcher for sure. Cant get a clear picture of what the engine was actually in originally so because of that the info you have given me for the timing chain cover might be my ticket with that conversion chart since i dont think i have the right cover. SO we shall see.

Want to thank everyone for the time and info they have offered up to the noob at hand. Really is appreciated info. Thanks!

Have you used a timing light at all? If you try moving the distributor around and don't know where your timing actually is, you're chasing a problem in the dark. Once you have TDC marked, and if you can gauge your timing from the 0-mark you made (10-15º initial with no vacuum advance will get you going in the right direction), then you should be able to get it running at least somewhat decent.

Also, what shape are the cap and rotor in?

Another thing that just came to mind, the 305 that was in my Malibu when I first got it had a bad intake lobe on #1... not enough to where it wouldn't run ok, it just didn't make as much power as it could've. There was a very faint miss on occasion at idle, and when it was cold it would barely run.

I didnt use the timing light yet. Did some messing with the dizzy while it would idle. Seemed to only be one place it would even run so I didnt think the light was needed. But I could be wrong. I have to get it right again cause i have it messed up and it wont run again for some reason.

Dizzy,Cap,rotor,wires,coil were all bought brand new less than 500 miles ago before i had to take it apart. Rotor was really dark so i replaced it and the plugs again but didnt change the cap.
