Mechanical Secondaries or Vacuum Secondaries?
If you don't know, there is a list number on the air horn that houses the choke blade.
The list number will face the front float bowl.
Give me that list number, and I will give you the info on your carb...

Re: Holley 4 barrel

To answer your orignal question...

See the attached picture...
=================================

The secondaries of your carb are controlled by a vacuum diaphragm.
That diaphragm is normally located on the passenger's side of the vehicle, an slightly to the rear of the centerline of the carb.
The top cover is about the size of a silver dollar.

The diaphragm pull on an actuator rod.
That rod pulls the secondary throttle shaft that opens the throttle blades.

To remove the actuator rod from the secondary throttle shaft, you must remove a 'C' clip.
That 'C' clip is very small, and easily damaged, so be careful.

Once the 'C' clip is removed, remove the actuator rod from the shaft linkage.
The rod can just hang in space until you decide to hook it back up again.

This secondary throttle shaft linkage MUST be secured to prevent the secondaries from opening.
Use a wire or 'zip' tie to keep them shut...

-----------------------------------

Just out of sheer curiosity, Why the heck do you want to disable the secondaries for anyway?....

Re: Holley 4 barrel

The reason being that I am getting gallons per mile. I am very light on the foot and can't figure out why I'm getting $%^&*@ gas mileage[img]/wwwthreads_images/icons/frown.gif[/img]

Re: Holley 4 barrel

It could be a lot of things...
That carb has the power valve protection, so it's probably not a blown power valve...

It could be a lot of things.
I don't think unhooking the secondaries is going to help, but it might show a problem...

Did you buy the carb new, or did someone have a chance to fiddle with it before you got it?

Washington state or Washington D.C.?

Re: Holley 4 barrel

I have had this Jeep for over two years and no one has messed with the carb while I have had it. Possible rebuild issue, i.e. float level. I have heard that the newer Holley 4010/4011 series get really good mileage, up to 25 miles per gallon on Chevy 350? Do you know about these carb? If I have the motor turned off and sitting with the key on position for a few minute, when I try to start the engine it has a hard time starting.
