Man, isn't that aggravating when you go to a rebuild or service diagram and they show you a later model of the carb. Grrrr. *

Lots of good info in those threads about deposits that build up in difficult to access passages. You might try an ultrasonic cleaner along with the suggestions in the threads.

I used to use piping hot beakers of carbon tet and methylene chloride in the sonicators to clean up nasty dirty greasy stuff on small metal pieces -- alas illegal stuff now (be very careful what solvents you choose as some will aggressively attack/destroy plastics).

* Aside: So, I have carefully collected a number of internet recommended manuals and pictures for cleaning my Mercedes transmission valve body assembly. I open it up and parts, springs, ball bearings, little plastic bits, etc. start dropping-out/launching onto the work table. I then see that the pics don't match the particular valve body version I have have. Nice.
