A kit will run you about $30 and include all the gaskets, some of the little bits and fasteners and an instruction manual. They are quite easy to work on, a fine carb in its day fitted to many vehicles, and it is rewarding to take a piece of old junk and make it work.
Now that is not saying that a shiny piece of Gucci kit like a Weber is not good. It is a great manufacturer. I have a Weber 40 from a Ferrari Daytona gracing Puthijeep's manifold and it is F A B. However it is not $30.
Bagusjeep has a 1981 Carter BBD non controlled which has been stripped, cleaned, adjusted and reassembled with new genuine paper gaskets (cut out with my penknife from real paper). The total rebuild cost $5 but it took 3 tries to get it to run right with float levels, idle tubes and inlet valve all needing some study. It has been fine for the last 4 years.
If the BBD did NOT have worn throttle shaft bushings (give that throttle shaft a wiggle, any sideways movement is an air gap that will make idle difficult to adjust) you may find that the best bangs per buck sit with trying a rebuild. For $30 it will at least give you a spare carb.
BagusJeep lives in Bali, the Land of Temples.
With a Jeep every prayer counts.
