From other posts about my ideling issue I had thought I checked the carb gasket but apparently it shows its ugly face now. I have put on 4 Qjet gaskets and all are leaking. Not in one spot. ALL AROUND. It does this when I turn off the motor. Its enough gas to fill up the reliefs on the intake. I have cranked on the bolts but no dice. It looks like the gasket is absorbing the gas and leaks it out. I see tiny tiny bubbes in the gas as it comes out. Any iders?
Carb Gasket. Cant stop a leak.

aqua, how would I go about sealing the well plugs? When i lifted the carb off, the entire carb underneigth was drenched in raw fuel.
For as many good things that I heard about the Edelbrock, for what reasons should it be a no go?

when you are getting gas on the entire base plate of the carb, its not the throttle plate shaft, and its not a sticky float. The part of throttle shafts that leak, 9 times out of 10 go to the outside of the carb. If a needle is sticking, the butterflys will be drenched in fuel, but again, that fuel is going to dump into the manifold not through the base plate gasket which is where I believe you are saying its all going. When the engine is running, throttle shaft leaks are rare, as the fuel is all pulled into the intake, even at idle. Usually when you shut it off, is when they occur. A sticking float, as I said won't do anything when the engine is off, but it will flood the butterflys at idle. above idle, the engine will be pulling the fuel in, and it doesn't usually leak.
Edelbrock Carbs work fine, but they are a fancy copy of a Carter Carb. a million pieces. They run fine when/if you get them set up right, but Holley is a hundred times easier to tune and set up. Not to mention that they only have about 10 pieces and you can buy parts for them at any auto parts store.

Well.. Although some of you guys like the holleys, it was hard to find anymore good info on the holley units besides this site. I search the web and buzzed over to Iboats and the Edelbrock seemed the hands down winner for stock to mild SBC's. I couldnt find anything bad about them. I called up the tech and explained my situation and he mentioned like everyone else, it could be a million things wrong and that the cost of rebuilding the entire thing wouldnt be cost effective esp on a Qjet. (I've never touched a carb before. Give me a labtop and EFI any day of the week) Soo I came home , drove down to summit and picked this up. They matched an online price of 289.99. + I used 40 summit bucks I had laying around.

I don't remember for sure, but I think the small red wire to the starter solenoid or the slave relay is keyed to the ign. switch run position, you'll just have to verify it with a tester and see if it opens the circuit when the key is off.
The thing I always liked about Holley's is that I could adjust my floats accurately while on the engine ( when the carb is not perfectly level) without having to take anything apart, and besides it being so easy to work on.
Nothing wrong with Edelbrock carbs either, I had an older one on the truck, and it was reliable..they have become very popular for a while now. I would of preferred a Holley, but the Edelbrock was alot cheaper at the time.
So good luck with it,
just don't take this one apart, and it will be fine..

As 5325 said, the edelbrock is like old Carter technology that I never liked anyway. My dad burned a van to the ground using a Carter that I could not convince him to get rid of.
Personal preference too. If I'm going to make power it is not going to be with edlebrock because I am going to want more than it can give me. That is just the way I have learned performance and it is not subject to change any time soon. I know what a lot of people say about those carbs ( and other things) but when I did drag racing work, we never sent a car down the track with an edelbrock when we were finished building. It might have come in the door with one but it didn't have it when it left our shop and the customer was very pleased with the results. I saw many a man who was surprised to learn that their edelbrock parts couldn't cut it.
Edlebrock can work ok for bone stock but I would never modify an engine for power using edelbrock.
Ok off my soap box
Mkos, if you haven't been into a carb then I wouldn't send you into the qjet to chase down well plugs. The process of getting the base plate off is involved enough that you could just get frustrated and not catch some details required to seal it for good. This is one aspect that a qjet shares with an edlebrock; a MILLION pieces. The edlebrock is probably easier to work on than a qjet too. Personally I like qjets. Regular or electronic.
Well plugs, are leaded plugs that block off the drill or casting points for the jets in the bottom of the fuel bowl. Through heat/expansion/contraction, etc the lead pieces will not hold fuel anymore. The bottom of the body has these ports where the lead must be peaned down tight again and epoxy sealer used to keep it in place. Some build kits come with a stiff pad that goes underneath these plugs to keep them tight. You might be well ahead of the money to get a different carb, if you don't know someone who can work on qjets well!
On your choke wire make sure that you don't take it off a curcuit that feeds the coil. The choke can pull the voltage down and you would have run issues. Your safe to fuse off of a circuit that is powered up from a solenoid using high power.

No!!!!!
I would never say a qjet is easy to work on. Once a person learns ALL about them it is still very engaging to fiddle with. :bigsmile: :bigsmile: :bigsmile:
You can walk away from the qjet and save yourself some misery. :bigsmile: :bigsmile: :winker:

That is usually the way it is.
If it hadn't been for factory training I would have done the same many years ago.
If someone is carb savy then some tips will help but if one has not been in a carb......... telling them to open up a qjet usually just creates a parts carb. :bigsmile: :bigsmile:

That's so true, I have some friends that are professional mechanics and they could'nt rebuild a Q-J even it their life depended on it, they would fix 1 issue, and then have 2 new problems pop up with it, by the time they were done, it was a parts carb. :laugher:
The problem is, most under-estimate how critical Every little part & adjustment is, and is a non-forgiving carb when one thing is not just right.
Ya kinda need to have a watchmakers mentality..

So did the new carb fix the problem?
