Holley 4000 Carburetors (2x4 Intake Manifold) Part 3 - Disassembly & Assessment
It's official! We have made it to post 100, a definite milestone in the work on the 1955 Ford Fairlane and other articles pertaining to FoMoCo in the 1950s. This is the third installment documenting the build of a 1957 Ford 2x4 Y Block intake manifold and carburetors.
This next video in our series contains information about the fuel bowl, accelerator pump, fuel discharge nozzles, float, jets, air horn, and a few specifics about the base. The clips are from the tear down and assessment of an ECZ 9510 1161 1 Holley 4000. Of the four carburetors I am disassembling this unit has the best fuel bowl but the worst base. The butterfly shaft is loose because the bore for the shaft has worn oblong in shape - a pretty common occurrence with these carburetors that have quite a few miles on them.
The second carburetor to tear down was an 1162 2 model.
The following video also contains some footage from another core. Disassembly of these units tends to be pretty straightforward. If you ever need to rebuild your Holley 4000 I highly suggest you take pictures or videos of the disassembly and the hardware as you work so reassembly will go as smoothly as possible. It amazes me how after so many years and "rebuilds" of these carburetors that parts get left out, things are modified or just plain installed incorrectly, etc. The kits are not cheap, nor is your time. You want to do this right the first time.
After all of the carbs were disassembled and the parts were assessed... speaking of assessed, take a look at the accelerator pump rods I collected. One of them was bent pretty badly and was determined unusable. Of course, this is another reason why it is a good practice to disassemble more than one core because of the need to "borrow" parts from one carburetor or another to give yourself a fine, working unit.
Anyway, after everything was checked over it was time for clean up and some coating work - we will cover this aspect (along with the vacuum signal modifications) in the next installment.
