Edelbrock dumping copious amounts of fuel

Rogue_Wulff · 08-10-2008, 05:35 PM

That's kinda where I was gonna start. The crap pump thats on the car, little square purolater, don't seem to hold steady pressure. There was a new Carter pump that was included, but I haven't swapped it out yet.
Currently, the pressure gauge reads anywhere from 5.5 to almost zero. Rather hard to tune a carb with the fuel pressure fluctuating that badly.
I think I have resolved part of the idle issue. Took the carb apart and sprayed the heck outta every passage available with carb cleaner. The carb is about 2 years old, but had never worked right, due to the timing issue. It had some gunk built up in the float bowls, so I assumed that it was also present in some of the passages internally.
In the long run, I have next to nothing in the entire car, so I don't mind having to tinker with a lot of stuff to make it run good. It belonged to a guy I know that lived about 100 miles away, and he had bought plenty of stuff in preparation for making the car a fun track car, that was still street legal. He also built a killer FD (~420RWHP) that was his DD. He was getting transfered to another base (Air Force) and didn't have anyway to get this car back to his home state of Pa. He gave it to me, along with all the goodies he had accumulated for it, just to keep it from having to go to the junkyard. I picked it up Tuesday night, and had it running after just a few hours of tinkering and studying about edelbrock's.
Come to think of it, 2 year old gas prolly doesn't help either. It had a little over 1/4 tank, and I only added 3 gallons of fresh fuel, and ~8 oz MMO.

Good job! My blue S is kinda the same way. A tinkerer's dream in which I've spent next to nothing to get runnning. Just lots of time.

Could you describe the manifold? I'd like to try an Edlebrock in NA form as the only experience I have with them is on top of a Camden so far.

Dang, somehow I completely missed that post.....
As mentioned in another thread, the intake is the RB 6 port 13B holley intake. A 1' spacer is required under the carb, to prevent interference between the carb linkage and the water outlet. I am using a 4 hole style spacer. I do not know if the 12A or 4 port 13B RB intakes will require the same spacer to keep the carb and water outlet seperated, but I would assume the carb mounting hieght is the same, which would make a spacer mandatory.

I have the RB intake manifold on my 12A. I do not have a spacer. Though I think I could get more power out of it if I used a two hole spacer to separate the primary and secondary runners.

I'm seriously considering getting my hands on a 12A RB intake, and trying the Edelbrock on it. I'm sure it make a huge improvement over the stock carb.
I have a couple Holley carbs that came along with the edelbrock, but my opinion is this: Edelbrock rules, Holley drools.
