 The idle jets actually control the mixture from idle to about 3000 rpm.

There's CB Performance in California which has some Dellorto parts.

Weaker ................................... Normal .... Similar  .......... Richer
   7850.5,     .10,     .9,     .4,     .1,     .3,     .6,     .7,     .2,     .8

A neat trick is to drill out the holes on the .8 to allow more air to pass, (weaker mixture). A mini machinists bit set is about $10.  I would get the smaller idle jets first. Re-read the idle jet selection part of the book.

If your car runs well when cold and then bogs down it's probably running rich.
