Manual Choke to Edelbrock 4bl Carb?
I tried to adjust it and it doens’t even move the butterfly when I turn it. I suspect the spring inside the choke cap is bad. I have a Maristar with It has dual fuel lines running to it. Which carb do I have on my boat? Is there a difference between marine and non-marine choke caps? Remove the choke heater and take it to an auto parts store. Other than the starter or alternator, you don’t need to buy engine parts from SkiDim and even those can be sourced locally- the rest are car parts. I would add the carburetor to the list of “needed” marine parts.
Edelbrock Electric Choke Problems
Edelbrock Carb an Fuel filter placement? September 8th, , How can I lean down my carburetor to get better mileage? First off, make sure the correct size, cfm carburetor is installed on the engine and be sure the idle mixture screws are properly adjusted see page 6 of the Owner’s Manual.
Manual chokes can be transformed into automatic electric choke operation with correct kits, and vice versa. Throttle lever: Linkage hook ups will bolt directly to the carburetor throttle lever and kickdown maximum three-speed automatic transmission.

Edelbrock 1405 Performer 600 CFM 4 Barrel Carburetor, Manual Choke
Be sure to save the illustrations separately. The opinions expressed here are my experiences, and your experiences may vary. I don’t put myself forward as the world’s leading expert on Holleys, but I do have some helpful ideas.
The Edelbrock # is a Performer Series CFM Carburetor with Manual Choke. This carb is a great performance part and is a perfect aftermarket upgrade for many applications. The # is a bolt-on easy to install item right out of the box.
All W-Machines should go right to the “AX” rod. The “DS” rod should only be used for racing. More adjustment of the secondary circuit can be made with the rod hanger. These hangers are coded A, B, C, etc. Therefore, an “A” hanger will pull the rods out sooner and higher than a “Z”. These are no longer available except for the “V” hanger, so off you go to the junk yard.
OK, now that you’ve acquired all these pieces, rebuilt the carb, installed bseline rods, jets, and the like, you are ready for final testing. Adjust all the fast idle, dash pot, vacuum break, etc. Now you can bolt the carb to the manifold. I suggest that a relatively SOFT gasket be used. Gasket offer a thicker unit with a composition which seems to hold up well.
Remember, a Q-Jet is vacuum controlled, so I suggest that you run an in-line fuel filter of very high fuel flow capacity.

That said, all of the below carbs are four-barrel models unless otherwise noted, and prices are either from the manufacturer or from an online store. Features include dual feed fuel inlets for constant high volume fuel delivery, large-capacity float bowls to eliminate fuel starvation, billet metering blocks for precise metering capacity, four corner idle and a billet baseplate with Idle-Eze for precise idle control, a quick-change vacuum secondary cover and non-stick gaskets for easy tuning, and large glass float-level sight windows for easy and safe fuel level adjustments.
Those goodies add up to balanced, high-velocity airflow, and exceptional fuel metering capacity for most street engines. In fact, these carbs are calibrated for to cid engines, including mild to inch Corvette big-blocks. Part number VE shown.
Q: How do I hook up my electric choke (voltage)? A: The Electric choke on our Performer Series and AVS carburetors needs to be hooked to a “keyed” (while the key is in the on position) volt power source, with a good ground.
It has the auto feature for the lights, and the switch function is good and tight. Is there something I am missing? Thanks, Hello Jon, Some of these ” Autolamp ” systems can be difficult to diagnose without the Factory Shop manual and wiring diagram as they use relays and amplifiers that can fail. Have you tried turning off the Autodim and the Autolight tabs at the main headlamp switch on the dash to find out if the headlamps operate properly in the manual position?
When you tested the foot switch did you do a continuity test in all positions? We have seen these switches lock up and seize on many vehicles. In any case and because you are a parts customer at Lincolnland I will ask George to send you copies of the necessary ” Autolamp ” section from the FoMoCo service manual. You will then see where the 4 amp inline fuse is located above the dimmer switch and be able to check if any critical components are unplugged etc.
This section should also offer diagnostic procedures. Sincerely, Posted by Bill at 1: The transmission was rebuilt and it changes smoothly under load but is a bit lumpy from neutral into reverse or forward and at lower speeds. Also excuse my ignorance but the transmission positions are of course low, then drive green dot and lastly a white solid dot.

The carburetor has been the Pandora’s box of performance bolt-ons. They’ve never been thought of as easy to tune or fun to run. They leaked, they ran inconsistently, and it almost took a Master’s degree in fuel system engineering to figure one out. Edelbrock’s newest entrant into the fuel-mixing arena has addressed many of the problems that plagued carburetors of old.
With a hot-air, electric, or water-heated choke, start the choke coil adjustment by turning the mark on the choke coil to the factory-specified position; or if you don’t have a service manual.
After running the hot wire to the accessory fuse at the fuse block I lost my backup lights and shift indicator lights. I disconnect the wire I get the lights back. Is there a better place in the fuse block to attach the choke lead? Local Hero November 3rd, , Mark November 3rd, , Fused of coarse also. Cars equipped with electric choke from the factory had it coming off the alternator.
Though, I’ve heard some people with Edelbrock carbs complain that the 6v put out by the STA port is not enough to run it. TallCowboy November 3rd, , Oh well, I ran mine off the switched post on the back of the ignition switch.
Setting Idle Mixture The Right Way
Connect clip end of choke ground wire to negative — spade terminal on choke housing. Install proper throttle and transmission linkage for your particular application. Throttle stud is removable and must be installed in the proper location.
Electric choke isn’t on ALL marine carbs and if I go out on my friends’ boat this weekend, I’ll shoot photos of the carbs with the thermostats on the intake manifolds. The electric choke thermostat is only on the boats that were spec’d that way, or the ones where it was added.
Be sure to adjust the idle-mixture screws equally so that they are balanced. If necessary, reset the idle speed to maintain the rpm speed. This may require going back and forth with the idle-mixture and idle-speed screws to achieve the best idle mixture. This photo also shows the location of the transition slot arrow 2. Ideal idle speed positions the throttle blades so that no more than 0.
Uncovering more or less of the slot can cause off-idle stumble problems. The float level on Holley and Demon carbs is easy to check and modify using the sight plugs on the side of the float bowl. Turn the float-level adjustment screw arrow clockwise to lower the float level and counterclockwise to raise it. Arrow A indicates where the hole can be drilled in the throttle blade to introduce more air into the engine when using a long-duration camshaft with low-idle vacuum.
The front port is for ported vacuum. The rear port is for manifold vacuum. When setting idle vacuum levels, hook the vacuum gauge to the manifold vacuum port. You might be surprised at how much better your street-driven engine will run with a properly adjusted idle mixture. The idle circuit is a crucial component to overall street engine operation and properly adjusting the idle mixture goes a long way toward improving throttle response, fuel mileage, and emissions.
