Hello

I'm in the middle of upgrading my Ford 289 with a Weber 48 IDA carburetor system. Unfortunately the system I bought was used on a Chevy SB and some Jet's went lost.

To complete the system and bring it up & running it would be very interesting for me to know the size of the required jets. Could some one please tell me, which one I would need to order / replace?

Today the following sizes are inserted:

Main Jet 170
Emulsion Tube F7
Air Corrector Jet 180

Idle Jet MISSING (size? F?)
Idle Jet Holder MISSING (size)

The Engine is a stroked 289 with a ratio of 10:1 and ~350HP.

Many thanks for your help
Regards
ALF

Search Weber jet survey in the Weber forum. This will give you an idea on where to start. There is a guy from Italy on ebay that sells weber jets for $2.50
