Weber re-build

Hi

I Have an old set of webers from that I want rebuilt for a 3.0

Can some one tell me the following I need to suit a 3.0 SC motor

1. Venturi size - I'm guessing 34-36mm
2. idle jet size
3. air correction jet size
4. Emulsion tube size

Who would sell set shafts and floats for the weber carbs?

What else do I need??

Cheers

matt

Hi Matt,

The answers to your questions really depend on the engine's configuration: cams, compression ratio. exhaust system, usage, as well as environmentals.

At the moment stock 78 3.0 SC with ssi's and 2in 2 out exhaust, street and track.

Later I will put in some JEs and GE60 cams.

Steve - does your company rebuild webers? I need some one to rebuild them.

cheers

Matt
