Super helpful video! You made absolute sense out of the jet and needle chart which confused me until I saw your video. THANK YOU!!

[happysailor]

Man...THANKS!!!!
You have delivered a super informative well filmed session again. I've the way you explain these things.

[skipthompson]

This is by far the best explanation I've seen on how to adjust an eddy carb. Thank you!!!

[Bogie]

I always thought my car ran pretty good and then I stumbled upon this video and realize that my vacuum advance was on the wrong port, what a difference thank you very much.

The AFB is the easiest carb to tune I've ever had in terms of an American carb. With their Strip Kit and the charts it is super simple. The only carb I've ever found that is easier to dial in are Webers. I had 42DCOE side drafts on a Chevy I had and, with beer in hand, I found them to be super.

Thanks this video has some very good info. I found lowering the fuel pressure to 3lbs. Helped the hot restart issue as well. Doesn't seem to creep as far up after shut down. The ethanol fuel is causing a lot of problems. For those of us running carbs these days.

Sir, First off, thank you for taking the time to help others... We appreciate you sharing your knowledge and experience. I have a 1992 Dodge D250 pickup w/360 (LA, not magnum) engine. It originally came with TBI, and ran pretty well until one day Pfffft. No power to coil or EFI. Literally replaced everything including the computer twice, still nothing. I purchased one of the Jegs HEI distributors (to fit a Dodge), an Edelbrock Performer intake, and at first a Holley 1460 Carb. Holly just pumped gas into the cylinders, and it chugged. Never could make it run right...
I am using the stock in-tank fuel pump, going through a filter, a bypass regulator (5psi), another filter, and then one of those "dial-style" deadhead regulators (just to be sure) before the carb. A buddy gave me a Carter/Edelbrock 9635S 4bbl, (600cfm) which I promptly put a kit into, and the truck is extremely happy. I did have to remove the vacuum advance off the dist. because it would hit the intake or the firewall. I "locked down" the timing slider inside the dist, but it still has centrifugal advance intact. With the Eddy/Carter carb, I can get a really nice idle, but it's a little too low (little under 500 RPM). If I attempt to raise it, it suddenly starts sputtering like it's running on about 4-5 cyl. Same thing happens if you lightly rest your foot on the gas pedal. just a little more throttle, and it's back to smooth, and accelerates quickly. Likewise if slowing down, slight pedal pressure (or being between 550-850 RPM) causes this sputtering miss, then it gets down into the idle circuit and smoothes out, but at really low RPM's.
The engine is bone stock, with 160, 000 miles, Automatic trans, and runs like a scared rabbit with the Edelbrock 4bbl, except for that blasted stutter just above idle. If I could just get it to idle up a little more and to stop that stuttering, It would be running perfect. Am I going to have to find a way to re-install the vacuum advance, or is there something that I am missing? Going down the highway, it purrs... and is 3-4 times more responsive now, than it ever was when it was TBI. Gonna need to do some mods to get my speedometer and overdrive to work again, as they were controlled by the ECU, but that sputtering drives me nuts! Thoughts?

Thank you. Not sure why Edelbrock stopped putting this tuning chart in the installation manual. It was frustrating just finding it on their website. Need to use a PC, not a phone. This solves alot of issues and shame on Edelbrock for removing this out of their manual. Thanks for the video

[c.pc.]

Sir I love the idea of 2 fuel filters this way everything is protected.

[crash]

very informative. I finally understand in plain english the tuning chart. I have had number of people explain this to me but couldn't understand it until now. thanks Muscle car solutions.

This is a fantastic video that I’ve been looking for. Tomorrow morning I go pick up my 1408 or 1480? Edelbrock tuning kit. I had no idea where to start now I do thank you very much. I put a new 383 ( with bigger cam and roller set up)in my Mopar and I got a terrible stumble off the line. I can’t even put it in gear unless it’s almost 1200 RPMs at idle without it dying. I will be referring back to your video and I will hope that my kit comes with that book. If not I will download the PDF as you said. Thanks again for the great video sir

[barneywarwick]

i have a 93 dodge Dakota with the 318 it's fule injection now how can i get more horsepower out of fule injection if i switch over to carboraitor i was told go with the holly 600cfm 4bbl electric choke and the air gap intake and a return line fule pump regulator the transmission is ran by the computer can i keep the transmission

[rustyridesgarage]

I live in Loveland Colorado whereabouts should my Jets be setted for a 600 CFM Edelbrock running into tunnel ram running into stock 350

[DesertRatFabrication]

And also what do you mean about the set-up spring to control the transition between cruise and power, thanks

[ianfurqueron]

Thanks for a video. I have a Triumph TR8 with an Edelbrock carb (replacing the OEM cross-ram dual Zenith Strombergs). My carb experience is with other British cars with SU and Zenith Strombergs, and despite dreaming of muscle cars in my youth, this is my first car with an American style 4 bbl.
I have been struggling with the car since I bought it last year. I came with no choke installed (manual linkage on the carb, but no cable installed), so cold starts have been a SOB. Once it does start, it runs pretty good, although it run super-lean during cruising. The previous owner installed a AFR gauge which is show the rating well in the 16:1 range (or higher) at speed. The temp gauge will also creep up almost to the point of over-heating. Oddly enough, in stop and go traffic with the engine idling, it richens up (13:1 or so) and the temp gauge is perfectly normal.
While watching the video, I paused it and went to look at the vacuum ports. Passenger side - capped. Driver side - open (with the vacuum hose to the distributor disconnected. The large center port - also open. Rear port - plugged (the power brakes are connected to a port on the manifold). Something tells me that completely open center port would represent a large vacuum leak? I know from my years fiddling with SUs and Z-Ss, vacuum leaks are the bane of carburetors. I swapped the distributor line to the passenger side port, moved the small cap and capped the large port.
I bought a tuning kit, but now I'm wondering if I really needed it... unfortunately, my interior is apart (fixing more previous owner "mods"), so it'll be a day or so before I can start the car and see if the capped ports makes a difference.
I wonder if a phenolic plate between the carb and the manifold might help, but unfortunately the space under the hood of a TR8 is tight.

I very much enjoyed your information, just got an old plymouth with 318 with edelbrock 1405 ( and year built carb 0462 how do I read what year this is

[armandomendoza]

Will this eddlebrock tuning guide work on a Rochester? I've noticed the the numbers kind of match on jets. Rods I can't remember. It has been years since I worked on a carburetor. I'm thinking of a EFI conversion to a carburetor set up.

[pooroledaddyfishing]

Great video, very helpful in understanding the chart. What should the timing be on the 454 I have, the vacuum advance is plugged at the distributor and both caps on the carb

[marks-ywij]

I'm very new to figuring out how to set up/ tune my edelbrock carb. I sont believe me secondaries are opening. When looking down the carb and going from idle to about 5500rpm I dont see them opening. Is this right? How can I fix this ?

[driftking]

Hey bro thanks alot amazing explanation, i appreciate...
