    I have 2 questions on my Edelbrock carb: 1. Where do I look for the model #? 2. The electric choke seems to work fine, but in order to come off high idle I have to physically move the linkage. Am I missing a spring or something? Or, is the linkage just binding (seems free)? Finally figured out why I couldn't seem to get the idle RPM right. Thanks for your help.

    I believe you have to stab the throttle while at high idle to get it to kick off, that's what I do anyway, as long as it's warmed up a little

      the model number is on the bottom left flange looking at it from the front.

        Holley's are stamped in the air horn. Edelbrock's are stamped into the base Left side from the front, passenger side from the drivers seat. Yes, you have to tap the gas pedal to get the fast idle off.

          Agree just tap the gas to get it to idle down. If you have to stab it then it need to be repaired, cleaned or adjusted.

            A properly adjusted choke, clean and dry linkage and fast idle cam, makes it work properly.

              Gravity is the control for a great number of carburetors and it can't overcome the friction of the contacting linkage, hence the need to tap the throttle to release the fast idle cam from the linkage.

                Shouldn't the choke turn off the fast idle?

                No. If you start the car let it run without touching the gas pedal the idle will stay up high all day long. You need to open the throttle slightly and release it it will come off the fast idle.

                As the choke warms up it gradually open the choke plate, but you need to slightly open the throttle and release for the idle speed to go down.

                stabbing the gas pedal to the floor or snapping it quickly is not how it is intended to operate and needs adjusting or cleaning/ repair.

                  Tool mans second quote below answered the question.
                  Only if your looking at it. :D Otherwise it is technically the left side of the car..... :rolleyes::D
                  Myk, the electric choke is t responsible for unloading the choke. If the spring is strong, it may. But as Toolman said above, tap the gas pedal.

                    I've never understood how all of that is supposed to work. What is the point of the choke, then; other than enriching the fuel mixture for cold starts? I just assumed that the electric choke on my 1411 was malfunctioning or something because I've always had to tap the gas to disengage the fast idle...

                      the choke does two things-

                      1- it closes the air door to richen the air/fuel mixture to the primary circuit

                      2- it sets the high idle position on the throttle stop (that's why you press the gas pedal to "set the choke" before starting

                      as the bi-metallic spring coils or uncoils (or time depending on the method in use) it gradually opens the air door.

                      as stated above the friction on the air door rod bearings is almost nothing.

                      the friction on the throttle stop is held under the much greater pressure of the throttle return spring.
                      when pressure is relieved, then gravity puts the throttle stop back to idle speed

                        I re-read the op's first post. I think his question about the fast idle was he expected it to come off fast idle by itself like the electric choke opens. Too much EFI nowadays and a few generations don't understand how a carb/choke/fast idle works.
                        Yes, the carb number is on the right side of the carb from the drivers seat "but" we always look at the carb from the front. Semantics is all that is. Let me add a little information to the above post to make it correct regardless of which way you look at the carburator.

                          Mike,
                          Do you have a 440 Source stroker 383? How do you like it?

                          I bought a Ohio Crank assy, probably before 440 was in business. It works very well for me. I'm running a six pack, entire Hughes valve train, 10.6:1, manual valvebody TF, GV OD unit. 4.30:1 Sure grip. Pulled 452 HP on Steve Morris' chassis dyno. Mike

                            Yowsa! I can see why you need that torque chain.

                            That’s the way it works. Just enrichen.
                            WTF is this Sarcastic reply for? And the rolling eyes?
