How do I tune my Edelbrock Carburetor? How many turns on each screw?

I have a 1983 Chevrolet Monte Carlo with a 650 cfm Edelbrock carburetor and about 300hp. Please don't send me a link to the Edelbrock carb Manual. I already looked at it and don't understand it.|||its hard to say how many turns cause all different size engines will be different, but to cut a long story short try this link, about half way down the page it will show you how to do it manually although they do use a dwell meter, i can't say i ever have though but the site may help you to understand the basic set up, if u have already seen the site then email ( you can see the link on my profile page ) and i'll run through it...


i'm a mechanic and in smash repair for 14yrs..|||you hook up a vacuum gauge to the intake and equally turn the screws until you get the highest vacuum reading on the gauge. buy a vacuum gauge then.. they only cost 20 dollars. you cannot properly tune a carbuerator without one. there are other ways to do it but unless you are technical you won't be able understand it or do it properly. you could try this but you need to do it with a vacuum gauge. tighten the screws up all the way, then back them off 2-3 complete revolutions. start the car and EQUALLY turn the screws up until the car runs steady then back the screws down to the point where it stumbles. turn the screws up equally until the motor runs smoothly. this will put you close. but you need to do it right.
