I got a Edelbrock carb when i swap my engine a few years ago but it seems that i can't get it to work like i want. Always get back fire when it's cold. Some said i should swap my carb for a Holley. I don't know what to do. I also have a hard time starting it when it's hot.

 

I just traded my Demon 800 for a Holley 600 and it was a Huge improvement. The Demon was WAY too much carb. for my set-up.

 

FWIW, the Edelbrock carb is based off the old Carter AFB. Personally, I think the Holley is a more "user friendly" design, but Edelbrock has a good reputation for standing behind their products.

I would consider shooting Edelbrock's tech line an e-mail, outlining your set-up, as well as the issues you're having, and see if they can give you some tips to get you running correctly.

Good luck...

 

Just fix what you have.

They are all "P.O.S. carbs" til you get them working right

 

I will try to fix my choke problem. I think it's why i get's backfire when it's cold.

 

Is it an automatic, thermally controlled choke, or an electric choke?

 

Electric. I hook it on the live ( when the key is on) wire from the wiper motor. I checked i do have power to the choke when the ignition is on.

 

If it works, I guess that's just fine, but, ideally, you want the power to come from a source that turns on once the engine starts.

I did something like that with a Pontiac T/A I used to own...I piggybacked on to the wiper motor terminal. What I didn't know, was at one point the choke power wire fell off, and the car started really hard. It was only a summer driver, so it wasn't that big a deal, but nonetheless annoying.

I found the problem a couple of months before I sold the car, at which point I did what I should have done in the beginning...I got one of those inline fuse with 6" of wire on each side of the fuse deals, and ran it through a grommet on the firewall, to a 12V source that was "on" with the ignition, at the fuse box. Car worked a lot better after that...

I have a brand new Edelbrock 600cfm electric choke. Replaced my worn out q-jet. I like it, now just getting tweaked into my car. Good luck.
