The Edelbrock 1405 I ordered from Ebay has arrived. Even though it was advertised as being completely refurbished, I ended up having to replace several pieces.
The step up piston assemblies were in bad shape and would not move freely. I replaced them with spares and they now work as they should.
Also replaced the metering rods with new components.
I also had to replace the accelerator pump plunger assembly. It looked well used, the plastic was discolored.
The idle mixture screws were also in need of replacement. I had a kit and installed those pieces.
I still need to check the pump jet assembly to make sure the components are useable.
