Carb question
OK folks I need some advice. I have a 600cfm edelbrock carb on my 71. The float is sticking and is dropping to much fuel into the ole motor. Here is my question.....
A. Should I rebuild the carb? Will it be just as good as new? Cost of around 49.99 B. Buy a new edelbrock 600cfm? Coast 299.00 C. Buy a Holley street/strip 600cfm for 259.00? I have heard that a carb is never the same when you rebuild them. What do you guys think? Thanks

Re: Carb question
Rebuild for sure. Float, rebuild kit, and time are a lot cheaper than a new carb. You sure its not a dirty needle & seat.

Re: Carb question
i would rebuild. i like holleys, but imo they require alot more fine tuning than edelbrocks. i've always liked edelbrock carbs for the street. i have an edelbrock on my motor that i've rebuilt once, and i think it works just as good or better than when it came out of the box.

Re: Carb question
rebuild............ that is a good carb, better than holley for the street, IMHO. personally I love a Q-Jet but you gotta know what your doing to get one tuned.

Re: Carb question
I had the same issue, remove the needle & seat clean them with some carb cleaner, check the float adjustment. That should cure it, if it doesnt at least you havent spent any money. After that find out whats making it stick or it will happen again. Mine was a fuel pick up sock that had rotted out and pieces were getting pulled into the fuel systm if thats the case you should find some of the pieces in your fuel filter

Re: Carb question
My friend had a 1405 that he was having problems with so he just gave it to me. I got a rebuild kit, tore it apart, shot it with some carb cleaner and it was still a little dirty, so I gave it a bath in Simple Green for an hour then blasted it with carb cleaner once more, put it back together and it has worked perfect for more than a year now. I think he regretted buying a new one after that.

Re: Carb question
Yup , rebuild it . Also make sure it doesn't have to much fuel pressure . These are easy carbs to go through and you will have a better understanding of how to tune it when your finished . You could buy the rebuild kit and the calibration kit for less than $100 and really dial that thing in .

Re: Carb question
I don't care for the Edelbrock knockoff of the Carter AFB. But... they are a more steetable carb with less tuning needed than a compareable Holley. I would rebuild it first.
Being a Holley guy... I would run a Holley 600cfm 1850 series carb. If you were going to replace it. But that's me. Gary |

Re: Carb question
I've been using the Edelbrock carbs for trucks/cars we buy to turn. They're simple, reasonably priced, and don't require a magician to tune. They are also easy to tear apart and clean/rebuild. I have a friend that is really good with them, so I find it helpful to drink beer and watch!

Re: Carb question
I agree, Edelbrock carbs are pretty much set and go, Holley’s are more intricate and are able to be tuned more precisely(from what I have heard). I’m way too impatient and uneducated on the Holley carbs. I do have an old Holley in the garage that I plan to rebuild, just so I can see what it takes.

Re: Carb question
After 4 Edelbrock carbs that were all junk, I use nothing but Holley. The Street Avenger series are great. I have a 570 Street Avenger on my 68. I had to bump up 3 jet sizes and set the idle and havn't touched it since.
The Holley also makes more power than any Edelbrock I had on it. Stay away from the "street/strip" carbs and double pumpers for street use. They are finicky to tune for the street.
