This is a Weber 32/36 Progressive DFEV Carburetor.
Here I tore down the carburetor to remove the jets.
Shown on the left is my carburetor's original jetting and on the right is a diagram showing the location of each jet.
These are the new jets I installed:
|1st Modification:||2nd and Current Modification:|
|Primary Idle - 50||Primary Idle - 55|
|Secondary Idle - 50||Secondary Idle - 60|
|Primary Main Jet - 125||Primary Main Jet - 125|
|Secondary Main Jet - 180||Secondary Main Jet - 180|
|Primary Air Jet - 160||Primary Air Jet - 160|
|Secondary Air Jet - 180||Secondary Air Jet - 180|
|Accelerator - Single Jet - 55||Accelerator - Double Jet - 55|
On the left is the separation of the idle jet and idle jet holder and shown on the right is an obstruction of the primary idle jet.
I have a fully heated intake manifold now.
Above are the intake manifold ends. I had a misfire on the R/S. I found that it was sucking air through the holes I pointed out in the picture. These holes were used as for guide pins on OEM heads. The aftermarket heads I have do not use the guide pins. I filled them with JB Weld for they will not suck air anymore.
Shown here is a diagram of the carburetor torn down to individual parts.
