Was wondering if anyone else has had any issues with new Edelbrock carbs lately? I bought a model 1411, which is a 750 carb with electric choke, for my 69 Super Bee 383 car.Installed it with a new filter and ran new steel lines to clean up the old rubber hose stuff. After installing and adjusting things seem to go very well until I drove it to work and got the car hot. It appears I either have a flooding issue or gas boiling in the bowls cause the car doesn't want to start after sitting for about 10 minutes or so. I can get it to go but you gotta crank for awhile and cram the acc. to the floor. Called the tech guys and they said to add a spacer to isolate some of the heat. I had a phenolic one so I did that. Ran the car last night some and it appeared to help but not totally correct my problem. I'm close to taking it back to O Reilly's for another but was just wondering if anyone else has run into this on these. I've had lots of Holleys and Carters over the years and haven't had this type of stuff. On my brand new carbs, it has been hookup adjust and go. Any thoughts? Thanks!

There is a big post somewhere here on Moparts last year about how bad the Edelbrock 750 carb is. Many owners have had a stumbling issue from a standing start. All the other carbs edelbrock sells are ok. Not sure about how to help you on the problem your having now.

run,dont walk and take that junk back.
get your cash back.
get a holley ASAP.

I have an edelbog on my car, and it has the same issues.

It also is a 750cfm. Last year I "borrowed" my dad's 600 cfm edelbrock for a while, and I was surprised how much better it ran with a different carb!

I now have the 750 back, I have been able to tweak some stuff to reduce the bog...but still there.

Soon to make some changes..Try going with the 800 or 650 cfm if you are hell bent on an edelbrock.

Hope this helps!

I wish I had seen that old post. Actually I don't have a stumbling problem at all. It works well when I can get it to run after it heats up.I'll mess with it this weekend and see what happens but back it'll go if I don't get things resolved by Monday.

The steel lines will absorb much more heat than rubber lines.

The 5/16 phenolic spacer seems to have cured my hard start but I must have a vacuum leak somewhere now. It runs fine but at the hit of the throttle at times I get a whistle. Maybe a slight leak around that spacer I put on.

Just in case you haven't done so already I think it would be a good idea to run a soft gasket on both sides of that plastic spacer to help prevent leaks from occuring.

Messed with that 750 carb the rest of the day after getting back from the Indy Mopar Swap. Made no headway with it so I took the carb back to O Reilly's last night. They didn't have anymore 750's in the store but they did have a model 1406 600cfm so I got that one. Stuck it on when I got back and after tweaking a little it seems to run well. Didn't notice any hard start after heat but we'll see,time will tell. Trying to get this car in shape for the Mopar Nats in August.

There are two models of 750... the 1411 is the "correct" one for your application, but there's a couple things I would have checked. First is float drop. Any carb that gets dropped just right could have a low float or two. Second is the step up springs. They are supposed to ship with the 5"Hg springs but I have seen the wrong ones in there before. Either of those two things being off could cause the issues you have. Heat is rarely a problem unless it's parked hot for an hour or more but doesnt cool down enough to need the choke. 10-15 minutes is not enough time for the fuel level (if filled properly) to evaporate that far.

When I got the carb to the store the counter guy said I could have taken it apart if I wanted to and it wouldn't void the warranty. The tech guy from Edelbrock didn't give me that impression but that'll be my course of action if I have an issue again. My thinking too was I just paid 300 bucks for this and I shouldn't have to disassemble and troubleshoot that far.I would like to know what the problem is though.It appears to have been an issue with that particular carb however. The 600 I got works fine after heated up and sitting.

the hard starting after 10-15 minuntes of setting with a hot engine is most likely a high float level. the fuel will heat up to the point of boiling. as this accures, it boils over into the ventures and loads the cylinders with exsess fuel. lowering the float normaly will fix the problem.

x2 I took my new 750 back and got the 600

I can tell I lost a little top end,but gain way more "drivabilty"

can stomp it from a 750-850 idle and never miss a beat all the way to 5000rpms banging gears

picked up low end and throttle responce

I got the same thing. Response pretty good and driveability better than the 750. I'll like the 600 as I drive to the Mopar Nationals this year over the 750 in the long run.

The Edelbrock 600 is a sweet little carburetor, but lacks at the top end. If you ever want a performance carb, get the 3310 Holley 750. Great all around carburetor for a 383!

I would have to say that with all my years working with carbs and mainly buying Carters and Holleys that this is the most I've had to do to any of those beyond the normal tweeking to get results.

and enjoy fuel leaks.
