hi guys I just put on a edelbrock performer intake and a edelbrock 1406 carb my original setup was a stock carter 2barrel the problem is now I went to go start the car and fuel was going everywhere like it was giving it too much fuel and I have a mechanical stock fuel pump could the pump be too much for it?
 
That carb will be fine with a mechanical pump up to 7psi at idle at least, probably more. It's doubtful the 2bbl pump can make 5. You'll have to pop the top off and check that the floats are not stuck open or the valves are
 
Had a couple loose screws in one eddy causing flooding.
Another had debris in the inlet valve. I had one apart a couple months ago,its been on a car for 15 years and it came apart without damaging gaskets.
 
Actually, the AFB style carburetors (Edelbrock or otherwise) don't like to see much over 5 PSI without problems. They share that malady with the Thermoquad. I've seen stock mechanical pumps overcome the needle and seats in these carburetors and flood them, so it's a possibility.

Put a fuel gauge on it and see what you have before taking anything apart. If the pressure is acceptable, look for other issues as already stated.

You didn't say but is the carburetor new?

"...First, verify, with a fuel pressure gauge that the pressure does not exceed 6.5 psi. Floats should be set to the factory spec of 7/16..."

Time to rebuild it even if the seller said it was rebuilt always assume it will need to be rebuilt that might solve a few of your problems so take it apart and tell us what you found as it will be a good experience.

Ok are these hard to take apart? I’ve never rebuilt a carb before

Check out you tube as there are tons of videos on how to rebuild a 1406. I rebuilt my first one a year ago and found everything I needed on you tube.
 
Used carb? A roll of the dice that it will work without a rebuild. Another vote for toomuch fuel pressure as well. A friend tuned on his Edelbrock for 6 hours one night and still couldn't get it to idle. Fuel pressure check said 7.5#. A new pump got it to 11#. A pressure regulator set to 5# and it was a different engine. A 500 horse 440 runs hard on 5#.

Ok where can you get the fuel pressure regulator? If the psi is too high also it’s hard to believe my 2 barrel could handle this and the edelbrock carb can’t weird.

Different carb. Holley can handle 7+ pounds. Your local parts store or Summit will have a regulator.

Put a GAUGE on it first. You may be jumping the gun getting a regulator. Diagnose it first, don't just throw parts at it.
 
those are pretty much the easiest carbs on the planet to rebuild. 9 times out of 10 you can take it apart, clean it out and get it running tits without even buying a kit. some carb cleaner and compressed air goes a long way. the float setting is all you really need to know other than basic skills. if youre dumping gas , there's **** stuck between one of the needles and seat , a hole in a float , or float level is all out of wack. as mentioned they like between 5 -5.5 lbs of pressure. I've never had a stock pump push fuel past a float bowl valve.

Me either; I have never seen more than 5psi from a 2bbl pump; most topped out at 3.5 to 4.

Ok I cleaned the carburetor it was a little dirty I checked the floats they didn’t have any holes I shook them no fuel in them I checked the float height is was good so I will try it again I will let you guys know

Did you check the inlet needle seats and valves? They are the brass plugs under the floats. I would remove the seat and valve to make sure nothing was sticking them open.

Except when some knob wraps T-tape around fittings.
