Again thanks for the suggestions. The reason that I returned the carb. rather than wait and try the pressure regulator was the Edelbrock tech was concerned that the idle screw had been closed tightly when I got it and since it wasn't supposed to leave the factory that way someone could have tightened it enough to either crack the aluminum base or strip it- apparently this is fairly easy to do. I simply didn't want to take a chance but after removing it and looking as closely as I could at it I didn't see any cracks. I still think that there was some problem with the floats (and the ethanol explanation is a scary one if it is correct because I had few hours on it) because I had raw gas sitting in the channels when I opened the secondaries- the tech. said it was normal to have a "little" but mine were completely flooded. Also the problem sometimes happened as soon as I started the engine and other times it would happen 5 miles after running it, no pattern. I hope the new carb. solves it but I'll also know what the fuel pressure is when I put it back together and may have a new explanation!
I would NEVER EVER put a carb on right out of the box. I always pop them open and check to make sure they are clean and set the floats. Just getting tossed around in shipping will put the floats off enough to cause problems.
Also guys, if this new carb does the same as the others, I would check to see if your just boiling the fuel..keep in mind todays ethanol gas boils around 20-30 degrees lower than the fuel of the past... Watch out for that boiling fuel, a plastic or phenolic spacer is a MUST.... Cheers and beers HOdge
New Carb. arrived yesterday from Summit just as they said it would so I'm really impressed by them. I'm not impressed with Edelbrock, despite their statements regarding the idle screws the left idle screw was closed (although not forced shut) and the right one was set at 2 turns, and the floats were 1/4 inch off and this did not come from being jostled in shipping. My son wanted me to return it again but I'm tired of shipping things back and forth so I went ahead and installed it, pressure is set at 4.5 lbs. and I'll run it to see if there are any more problems. If you don't hear from me you can ***ume it is working fine, if you see a carb. flying thru the air you'll know what happened! Good luck to all going to Austin, wish I could be there with you.
I have a 1406 that I put on 13k miles ago and have not touched a screw on it. Just bolted it down and used it. Great carb. I am getting ready to buy another one next week. I hope I have just as good of luck. The plastic spacer is a good idea. Mine would start loading up slightly in the really hot summer when stopped in traffic. The spacer cured the only small issue i"ve had. Good luck.
I don't care what pump you are running, or what ANYBODY says; if you are running an Edelbrock you have to run a regulator. Get a good quality one with a gauge, at that. Do not buy the cheap, part's store chrome ones. Hook it up, and set it to 5 psi., then, and before you start it up, pull the carb cover, remove any debris and set the float level. Ifyou still have trouble, then you can start to diagnose it from there. Are we starting to sound like broken records, Zman?
I had this problem and it would fill the engine up with gas. I hit mine with a hammer and it never did it again.
I have one on my car now ... (got a good deal off a friend, carb, intake, air cleaner and valve covers) ... I hate it. I have always run Holleys up till now and looking forward to going back to them ... and, as I understand it, I am far from the first person to feel this way.
Did you tune it? No carburetor is good-to-go right out of the box, or right off of your buddies car. Those of you who happen to be getting acceptable results from a carburetor that came right out of a box, you are very lucky. Luck, as I have said before, is neither a business plan, nor a success or survival strategy.
That is the stuck needle situation i've experienced. I thought it was a float, but I pulled the top off, and the float would hang just fine. The needle would be stuck to its seat though. Was this in the fall or winter? It was the worst for me then, when they changed the gasoline to winterblend. I've used these carbs on a chevy and a ford, and I like them. I replaced a rotted, but otherwise great q-jet on the chevy, and a holley gasoline faucet on the ford.
Oh **** took the 52 out on the weekend and guess what, yup flooded and died, so it was a trip home on the flat bed with under an hour run time. Within a 1/2 hour it was running again and very luck it just filled the exhuast and not the new synthetic oil. So I am off to Hmmm the rod shop for a regulator I am not going to chance it again. Hell not only that it was embarrasing. In My case it looked like one of the metering rods was hung up. I removed it and back fed air through the carb. Idrove the car the following day for over a hundred miles and it seemed ok. Other than the odd time I would get a wiff of gas fumes at 60mph. Any thoughts on this.
Hahahahahahahahahaha!!!! Oh, God Damn!! HAHAHAHAHAHAHAHAHahahahahahaahahahah!!! Oh... I just pissed myself! Those Edelbrock guys should have their own sitcom! ~Jason
What car are you talking about? The one in your Avitar? It's old, have you checked the tank? When I got my 32 Moper the tank was rusty. I took it to a local shop and they made me a new one, worked well. I've had the car since 1977 and down to the frame 3 times. During each build I coated the tank inside with motor oil. This last build I had problems like yours. I used a kit from POR 15 to coat the inside of the tank and it's working. You'd think a good filter would stop all the stuff. It doesn't. My solution to your problem would be to put a Holly on the car. But we've had this discussion before.
You can send it my way if you dont want it,, lol Seriously, hope you solved it, Always interested to hear when problems get solved,, Well....??
Yes it is the car in my avitar 427 b.b with a 750cfm and a new gas tank but I certainly here you on the fuel filters I run 3 of them and I am seriously thinking of a marine fuel water seporator as well. We ran these on our race cars for years.
LOL! Oh, man - I couldn't help myself. Sorry, guys. I was laughing at what the Edelbrock tech was saying, not anybody here. Oh, man... I've heard a LOT of whoppers in my day (I have 6-year-old twin daughters), but that one just took the cake! Granted, I'm not the biggest fan of Edelbrock carbs (I much prefer the real Carters), but that was just... well, I don't know what it was, but it wasn't right! ~Jason
Haven't had any problems so far but I've only put 50 miles on it. I add the holly regulator so I'm sure some of you think that solved the problem, I'm still betting that the needle valves were not macined because they were sticking. either way i cartainly can't say i'm impressed with Edelbrock! If anything changes I'll let you know. Don't blame the tech, Edelbrock states you don't need a regulator in their manuals for both the pump and the carb. I'm not impressed with them.
When I was running an AFB (Edelbrock copied these) with a Carter mech. pump I used a Holley pump from Summit - end of issues.
http://www.amazon.com/Spectre-2517-Chrome-Pressure-Regulator/dp/B000CQ46H0 I have used one of these on my ot 72 chevy work truck for years, with no problems, good quality and it's 22$ + sh
I wanted to give my final update, the carb. ran approx. 300 miles with no problems. I then installed a spacer that several of you recommended to help with boil-out (I was having that problem too) and while I was working on it I decided to pull the regulator out to see what would happen. As you might gues after approximately 200 miles I've had not problems, presuure is running 5-7 lbs. After all this I had a retired mechanic from Roush tell me that carburetors today are junk, he figures you have to get 3 to find a good one. As for having to make major adjustments on them after taking them out of the box he is like me- if you spend that kind of money you shouldn't have to be making major adjustments. After all this I think my next carb. will be a Holley.
There is no guarantee that you wont have to make the same number, or more, adjustments to a Holley as you did the Edelbrock. Part of hot rodding is tuning. If it were all bolt-on and go, it would be easy, everybody would have one of these damn things, and it would not be cool anymore. I have installed over 100 Edelbrock carburetors in the the last 10 years. Not one single one of them was junk. Not a one of them, nor the 30-40 Holleys I have installed, did not require some sort of adjustment.
