Just wondering if any of you carb guys can give me a hint or where to begin when learning how to tune a carb. I want to learn how to tune my new holley but dont really know where to begin. Are there any good books or websites that you guys can recommend? Thanks for the help.

yes first thing is which carb did you get

 

Yep, good book, you need to buy it.

if you got a 302 or something along those lines, a 600cfm carb is more than enough carb for it.

 

yes the 600cfm vacum secondaries is more than enough for my car sometimes i wish it didnt put out so much gas im only getting 12mpg

 

Do you have a vacum gauge?

 

Its a holley 650cfm with an electric choke. I decided to go with a 650 in anticipation of heads and a cam in a few months. And thanks for the website 2 kwik. No i do not have a vacum gauge.

 

get one there not very much. you need one to tune your carb right

 

ok i'll pick one up. what do i use it for? sorry im a newb when it comes to carbs but i really want to learn.

 

Connect your vacum gauge and then begin to tune your carb (by opening and closing the needles) do them one at a time and go back and do it again untill you have the highest vacum possible. then once finished adjust your timing and do it again.
