Time to Ditch The Edelbrock!

Interesting. Those were not on the needles when I opened the carb the first time.

If that's right (not doubting you), I'd be surprised it ran at all. That simple, but effective little wire clip is the 'link' between the float, and valve. Pretty sure on the float arms, there's a small bent tab (close to the pivot), and the wire slips over it.
Wire clip opens the valve, and the tab closes it.
With all in place, you can move the float up and down, watching the valve move. Otherwise, that valve would just sit there...closed.
Important thing is...once in place...float adjustment!
 
I'll just mention that I've rebuilt a ton of carbs eldy and those clips are not in most the new rebuild kits do away with them there on a different style bar/clip I don't have any pictures I was unsure back when I first in countered this eldy said the rebuild kit is a up grade to some of the old internal s . Wish I was more help but if. I'm starting to think you found your problem
 
First dealing with eddys on my current build. But, did go into both of them, to do a little modifying, and check the float settings. Wire clips on all four needles.
 
I run the floats at 7/32" instead of 7/16". This will bring the main circuit in quicker.

Eddy's don't like fuel pressure much over 5-6. It's cheap to buy a regulator and gauge. I have stock fuel pumps that are putting out 7 and it causes all sorts of issues if not regulated...
 
I replaced the seats and needles, and added the clips, and the carb is still flooding on the driver's side. In a last-ditch effort, I went to O'Reillys and got some new floats and put those in. When I was cleaning up, I picked up the old floats and noticed one was heavier than the other. I shook it, and it feels like it's about 3/4 filled with gas.

I can't find a hole anywhere, and I've shaken it in every direction and can't get a drop to come out of it, so I have no idea how gas is getting in there but it is. So hopefully when I put the carb on tomorrow the carb will work.
 
Gas isn't like water it will find the smallest hole. You probably wouldn't see it with a magnifying glass. Keep us posted, curious minds want to know.
 
That explains it. Now off to happy motoring. In my experience with these carbs you can run 7 PSI (and that is what is recommended). Remember that float level AND fuel pressure affect the average fuel level in the main well and that in turn provides proper mixture. Do not discount these very important adjustments.

[QUOTE="dvw, post; Weigh the floats. Is one float heavier than the other?[/QUOTE]
 
Here's what I think happened. The car was running fine, then we had a tornado come through, then it wasn't. When the tornado hit, there was a severe drop in pressure. Our ears popped, the window fans reversed, and it felt like all the air was rushing out of the house. I'm wondering if there was a small crack in the solder on that float, and when the pressure dropped it opened that crack, the gas got in, then when the pressure normalized the crack closed? There is no gas at all coming out of the float, regardless of how I hold it.
 
What are you running? I'm not real familiar with all the permutations.
I know they make one that is a Q jet style.
I like Q jets. So is it just a quality problem?

In full disclosure, I don't like Holley carbs simply because of the side float arrangement for one thing.
From what I heard (and experienced) that a is potential leakage point and fire problem.
And on top of that I want a spread bore since, realistically, don't "we" mostly drive on the street anyway.

I've got hundreds of thousands of miles on Q jets with no problems.
 
Float level affects how rich a car runs, I heard.
That fuel in the bowl has some "head pressure".
The more fuel the richer. I can't say for sure.

This works on the plastic (?) floats too.
I've had ONE of those go bad.
It was on a AMC Gremlin. That's how long ago.
Happened right after I "rebuilt" the carb and did not put a new float in.
Figures.
That being said I've reused many plastic floats in Q jets with no problem.

 
I've had both and the Holley's do not like dirt, but seem easier to tune. Maybe just me.
 
The carb seems to be running okay now with the new floats, which is good. Now we'll see how long it lasts... hopefully longer than two months again. :)

I did find a new trick from a youtube video (I love those things). When you take the top of the carb off, reattach the fuel line and blow through it. With the floats down, you should be able to blow right through the line. Turn it over so the floats are up and you shouldn't be able to get any air in. Quick way to check how well the needles are seating.

This will also be the first time I've run the carb with those needle clips installed. Whoever rebuilt the carb before I got it left them off, for what reason I have no idea.
 
It should be fine now. The Carter AFB/AVS designs are pretty much time tested. I'm by no means a carb expert in any way but I've had and rebuilt Carters, Edelbrocks, Quadrajets and Holleys and the Carter/Edelbrocks are probably one of the easiest to work on. The one piece bottom casting eliminates a lot of issues with leaking bottom plugs, warped metering plates and fuel bowls and so forth. One thing I have learned over the years is that what sometimes makes the biggest difference in the success of a re-build is taking the time to carefully make all the fine adjustments they outline in the instructions - accelerator pump height, float height & drop, choke closure, etc. The details make a lot of difference.

More wive's tails. Side hung floats have been used for decades and are NOT a fire hazard. Holley performance carburetor are mostly center hung. Certain applications work better with one option or the other; i.e., off-road, drag racing, road racing or marine use. Repeating things that are heard while 'bench racing' is not productive...

Agreed, never had an issue sealing one up especially with the gaskets they use now days but have had brand new Edelbrocks leak out of the throttle shaft. All manufacturers have their bad days.
