Leaking carb
I have had my 67. 327/350 in storage for four years. After new gas and a new battery it started. Yesterday I cleaned it and today took it to a car show in town. While cleaning the air cleaner, I noticed gas on the intake manifold. Obviously I have a leak from my Holley carburetor.
Any ideas what to look for while I'm just sitting here??

tighten up the 4 screws holding the fuel bowls to the main body. Could also be leaking from the accelerator pump on the front bowl, or the crossover tube o-rings on the driver side.

If accelerator pump gasket is weeping/leaking you will need to remove the carb to tighten these small screws up.
Then run the engine with the air filter removed and look over the rest of the carb.

Take a screwdriver and tighten the 4 primary and 4 secondary fuel bowl screws. I need to do this frequently on my own car.

I use no wrench, just a screwdriver hand tight and snug them up. Once done for the summer, all is good. But once the cooler fall and winter temps arrive, I need to do it again..........maybe a couple of times each winter.Forgot one time, and drove down the street with a small gas stream (no drip
) running down the passenger side of the block. 
Not good. Haven't forgotten since. Now if the cars has been sitting a month or so I check the engine and concrete before getting on the street.Larry

I don't want to scare you, but you better have a fire extinguisher in the car. It may well be time to replace all the rubber gas line up front and the section at the tank feed. Dennis

If it turns out to be leaking from between the fuel bowls and main body, try the blue gaskets. They're not correct but do a better job of sealing. As an added bonus, they're reusable. They don't tear apart when you pull a bowl off.

I did this in my garage and was alone so I didn't start the car up since I have no one there with a fire extinguisher to keep a look out.
I will be back up there in two weeks and I'll bring a pair of the bvlue gaskets just to be on the safe side. I'll get a watcher with a fire extinguisher and crank it up.

It appeared that the leaking was from the front fuel bowls. That is a guess since that is where the majority of the leaked fuel was. The screws were snug but not tight. I tightened them just a bit.

As for a fire extinguisher, I recommend something like a CO2 or Halon Unit versus the typical dry chemical. WAY LESS MESS AND CLEANUP if you have to use it. That is why I keep only these in my garage.
If the car could backfire, start it with the air cleaner on, and then remove the air cleaner to check for and find any small leaks.
FWIW.

EDIT: What area of Chicago do you live?? I grew up on the South Side.................although it is a bit "rough" living there now. Still have family in the area though.

I think you are a bit paranoid with needing the fire extinguisher, but having a "watcher" is a good idea if the car sits a long time and is a bit rough on restart. That way you can remain in the car and control the RPM better, etc.

I live on the far northwest side of the city. You are right, the South Side is pretty rough now.
