Carburetor flooding

[chevyconvert]

following up on http://www.cuda-challenger.com/cc/index.php?topic=18248.0
Front carb had been flooding since trying to adjust float.
Changed the front carbs needle and seat.
Couldn't get it started for several days to adjust the float.
Finally got it started and sat a minute in the drivers seat warming it up.
So happy that it started, had forgot the original problem...flooding.
Anyways the front carb was flooding BIG TIME!
Shut it off...gas pooled in all the manifold runners etc.
Gas actually was coming out one of the tail pipes!

Besides an oil change...what else should I do to get the gas outta the engine?

Could I have caused any permanent damage?

I'm pulling the bowl at this point.Any help on adjusting the float dry with the bowl off would be helpful.

Anyone know the correct Holley # or orifice size for the needle and seat for the front carb. Speed shop was unsure.
Thanks Guys (and Gals!)

Quick way to adjust the level with the bowl off: Turn it upside down and screw the needle and seat in until the float rises up about half way. Then install and adjust with the bowl screw off till it just trickles out.

Change that fuel filter again while you're at it. Dirt causes flooding everytime.   Some newer style needles and seats used VITON RUBBER on the tips.  In My race car, running gas, I always bought the bigger alcohol steel seats, without that sticky rubber in them.

Thanks S.D.
 I assume you mean the the ones that are just rounded vs. coming to a point.

Answers still needed to:
Any idea what orifice size needle/seat the front carb is supposed to have?
The new one I put in was .110

I just pulled all the plugs to let the gas dry out of the cylinders.
I removed the front carbs float bowl.
Do the black floats go bad? How to test..?
Should I replace it just in case?
I'm still wondering if I could have done any permanent damage or if I should do anything else besides change the oil.....

I know I'm asking alot of questions, but there's alot of knowledge out there ~!

[Chryco Psycho]

you wil Not have done any permanent damage
changing oil is a good idea
Make sure the float doen`t have a hole in it so it sinks in the fuel put in a jar with fuel in it & make sure it floats , the part # I have for the needle & seat is 6-504, although virtually any needle & seat will work in there

[ShelbyDogg]

I agree with CP, Since you had it running while it was flooding, probably no damage at all. I bet you had to throttle it like crazy to keep it running, didn't you?   We all know about flooding problems with old cars.   Don't forget to change the fuel filter.

Thanks SD..yeah I had to throttle it alright

Darn, forgot to pick up the fuel filter. It has one of those plastic in-line ones now.
I've heard the metal ones are better, but it's nice to see the fuel too.
Any recommendations on type of filter?
Also, do you think there is raw gas pooled in the cylinders since it made it's way outta the tailpipe?
  If so how long to dry out with the plugs pulled?
Should I turn it over with the plugs out?
Should I squirt some oil in each plug hole since the gas probably washed the walls down?

Man! I feel like a pain-in-the-arse with all theses questions !
I just like to do things right ya know, and I appreciate the input 

[ShelbyDogg]

I use metal filters so I can crank the clamps down. I check for fuel at the squirters. Don't worry about the gas in the intake. It was running when it died, so crank it for 3  seconds, put those plugs back in and start it up.  That tailpipe liquid was probably water and raw gas already went through the cylinders. Alot of worry over nothing.

It was raw gas that came out the left tail pipe...not condensation.

Bought a new float just for insurance.

Thanks again.

Maybe too much fuel pressure.  Have you recently changed/altered your fuel delivery system?     

[chevyconvert]

nope, but this could have been a problem for a long time.

I had a '71 Demon that ran rich and was very sensitive to float level.  It turned out that the mechanical pump put out way too much pressure and needed a regulator.

[chevyconvert]

Thanks Matt, definitly need to check that.
What's a 440 s'posed to be....around 7 psi? I know someone here told me once..

[Chryco Psycho]

6 psi for carbs

[chevyconvert]

if i have more than the six psi, then do i need a regulator?
do they go inline between the pump and the carbs?
Recommend any certain type?

You have the location correct. 6 PSI is the ideal, but your carbs must be touchy if a little over that causes problems. I typically have around 8 or 9 PSI at start-up, then it goes down to 6. You can find regulators in Summit's or Jeg's catalog. The price range varies widely too. I also recommend some type of inline fuel pressure gauge, so you know where your pressure is when you are adjusting the regulator.
