This is from a Weber conversion booklet put out by Borg Warner (they used to be the Australian Weber agents) sometime in the early 80's giving a listing of suggested jet settings for various tunes, including Corolla's (1200) for twin 40mmDCOE on both stock and full competition engine, Celica's etc amongst many others. I have put the whole listing up in case you have something else of interest in the shed.

 

It lists suggested choke, secondary venturi and assorted jet sizes. This should give you a bit of an idea for a reasonable state of tune prior to heading along to your friendly local dyno.

Thanks for this! was actually going to ask about base settings for twin 40s on a 4k now i have base to work from :y:

Weber bits are bloody expensive, so knowing a baseline to work from is exceptionally helpful!
