Not sure. I'll check on that compensator.

Found some things out yesterday with my hard start when my 69 Super Bee 383 has sat for 15-20 minutes after running for awhile. With the Edelbrock (Brand new out of the box) I have to put the pedal to the floor and grind to get it the car to start. I rechecked the fuel pressure and saw 6psi. I hooked up a regulator and adjusted to 4.5 psi. Same result. No start Hot. I went ahead and checked the motor compression, just because I hadn't in a long time, and that was good in all cylinders. At that point I cried UNCLE and put my Holley back on paying close attention to starting hot and it does crank over a few times but starts without planting your foot and grinding away. This brings me to My next theory, Heat riser valve stuck partially shut. The Eddy bowls are hung on the side of the carb, the Holley front to back more away from the crossover of the intake. My heatriser valve assy appears to be gone except were the flapper arm rod would be sticking out of the exhaust manifold , thats still in place and stuck, can't move it. Sounds like it could be time to pull that loose and make sure. The exhaust has no crossover as well so I may be able just to check the amount of exhaust I get but the valve may well not be shut all the way cause when hot I don't notice any issues with how the car runs once it gets going.

Yes Tim you are hard headed , it's that 1411 carb , it's a PIECE OF CRAP , PERIOD , end of story. Look for the carb test fast68plymouth did some years ago and he specifically had horrible results with an ebrock preformer 750.

The heat riser is making the problem 2 fold, you have the heat passage open under the intake ... i assume ... and the new fuel formulation getting boiled out of the carb. insulating the crab from the intake don't matter , heat RISES , the heat from the open passage is rising up thru the carb and it's evaporating the fuel.

Actually I have a 600 Eddy now. I took that 750 back to O Reillys but I'm getting the same thing with this 600.Two new carbs with same issue sounds unlikely and the heat riser flapper not being open all the way could explain why the Holley works and the Eddy's don't. If that's open, I'm taking the 600 back for either a refund or a new Holley. Or just rebuild my old Holley and move on.

I tell ya, the 3310 Holley 750 carb will do you way better than that 750 Edelbrock. I ran that Edelbrock 750 for several months, tuning, tuning, tuning. Hard starts too. Switched to the 3310. Night and day! No hard starts! I love my 3310 Holley 750!

Yep. I replaced some leaky gaskets on my Holley and am now off and running. Heat rizer valve open so that is that. My 600 Eddy is in the box to go back. It's only 2 weeks old.Allot of headaches trying to put a new one on. The first 750 Eddy I had about a month ago Idled like crap and had the hot start issue. This 600 just has the hard start. Took my new age Carter AFB off my 68 bee and ran it on the 69 also. Redid the Holley I had on it to start with and am now back and running with no hot start issues. That'll be my last attempt at messing with an Eddy. I just hope after the 2nd try they'll either give me my money back or a new Holley. This Eddy is a boat anchor.

Thanks for all the input.After putting my old Holley back on I took that Edelbrock 1406 back today and got my money back. No more of those for me. Since there are no more Carters available I guess, Holley here I come, in the future.

So how's the holley run?

Holley runs great. No problems.

List # is 4749-3. What CFM is that? I looked it up in my Holley carb book but it didn't list that model. Thanks.

sure it's not HLY-0-4779C

List 4749 is on the air horn. I do know it's a fairly old carb.

Thanks Scott!!

I needs to gets me one of them holley gas holes fer my 440

I just got my first one its a spredbore 650 manual 2ndarys double pumper

is the 3310 the one with the duel feed line??

so that carb is a replacement for a mopar or would it have come on a mopar stock

I guess I gots lot to lean on these gas holes

Some of the 70's had a stock 4BBL but most were Carter AVS,Thermoquads or AFB's. I used to have a 70 Roadrunner that had a stock Holley on it. This 69 Super Bee a Carter AVS.

My 70 383 Charger S/E 4 speed had a holley stock. I think they were rated at 580?

I'm thinking of getting a new Holley now after all the issues with the Edelbrock. I've taken that back to the parts store. Whats the best all round Holley carb out there for a stock 383 HP car? I'm thinking Double pumper. I've had good luck with those in the past.

Stock 383 should like an 650dp

Holley 670 Street Avenger for a stock 383!!!

Why not a 750?
