My favorite Quadrajet rebuilding tools:

<< < (3/3)

Kenth:
The problem is that the zinc casting in the float housing gets compressed if the screws at the front are tightened too much.
How do you stretch the zinc casting with this tool?

Pav8427:
For the airhorn,it is just a bolt down with a few well place Kant Twist clamps.
The main body is actually sandwitched between 2 plates.
Most I have torn down the throttle plates are flat.
I use an oven and heat to 250* and let cool over night.
Most airhorns still require some flat filing at the front bolt holes.

Kenth:
So it's a matter of squeezing the float housing together so that the all over height gets the same as the previously squeezed front corners?

Shiny:
What is the specific alloy used for the parts that warp easily (ie airhorn)?  Is it a zinc-based or aluminum-based alloy?  I expect zinc alloys would creep faster at low temperatures.  250 F overnight sounds like the material moves pretty easily!

Pav8427:
Yes just pulling the two surgaces parallel with help of heat.
The 250* is only initial heating of jig/carb then letting cool over night in the oven.
Actually the most time involved in the whole process.
