i have a mechanical holley pump
when i had my car at the carb shop, she started spurtin gas everywhere
so they recorded the pressure from the fuel pump and it was around 9

holleys says -
"HI,
thanks for your e-mail
it needs 5.5 to 6.0 PSI
if it floods @ that PSI
it must have trash in the needle & seat
of float level set too high


To adjust the N&S take the fuel bowl off and hold it upside down & level
then bend the tang on the float so the float is level in the center of the fuel bowl.
this will get you back to a starting place.
Thanks for being a Holley customer
If there is anything else I can help with please let me know
Thanks Ricky"

but see, if I do this, the work I got done at the carb shop is pointless. I paid $180 for nothing? Should I call the shop and have them do this?

Can't say I'm at all surprised at the response from Holley, that's what it sounded like to me from the beginning.
You bought a new in the box carb, and it got shipped to you after it was run from the place you bought it from, correct? It's quite possible that the shipper dropped or threw the box around (not that that ever happens), and that could have tweaked a float or two out of adjustment or got a piece of crud stuck in the seat.
It's an internal issue of the carb, no fault of the carb shop the way it looks.
I think I just found delivery confirmation video of your carb being shipped: http://www.youtube.com/watch?v=QxPa9Vc1v8Y

soooo much crud in the needle and seat
cleaned her out, filled up my tank... drove amazing for 3 or so miles, stalled twice shortly after
holleys cant tank the low quality gas in southern california
im gonna return the carb, have a custom built rochester build for $350... masssssive secondaries
threw $190 down the toilet

Wait a second first....where is the "crud" coming from? And what kind is it, slime, chunks? You sure you're not getting debris that's inside your fuel lines or tank? A good small micron filter placed shortly before the carb inlet should stop the kind of crud that can gunk up the needle and seat. What you are getting isn't a problem that's specific to only a certain brand of carburetor. What are you using for a filter anyway, an old sock or window screen?

you can slightly see ONE of the TWO new fuel filters in this picture

Keep the Holley, it's a good carburetor, and your crud issue isn't the carb's fault. You didn't say what kind of crap you're getting. It's possible you might have a lot of crap in the tank, or rusty fuel lines?
That filter looks like the Spectre brand like from AutoZone, or one like it. Looking up specs on that type doesn't turn up any particulars to the filtering capability, as much as I could find. Could be there's nothing to brag about, unless you know what that one is rated at?
You could use a filter like that before the fuel pump to keep any chunks from damaging it. And a filter like this 5 micron one right before the carb: http://www.summitracing.com/parts/SUM-G1512/
For reference, one micron (micrometer) is one thousandth of a millimeter, and a human hair is about 50 microns.

the fuel lines were checked when we couldnt start the car (turned out to be a bad regulator)
The stuff in the seat was tiny debris, i could barely even see it, if it were dry it'd probably be a yellow powder...

now that you say crap in the tank, when we had the bad regulator, a mechanic at the carb shop pounded my gas tank repeatedly over and over saying i had no gas (i know i did)
he probably loosened a bunch of crud up, huh?
how can i go about cleaning out the tank?....
