Default ROCHESTER 2 Barrel adjustment procedure

wonder if anyone might point to any adjustment tutorials for a ROCHESTER 2 barrel carbureter on my chevy 350?
just basically how to set one up properly, float, air mixture, choke trouble shoot etc.

The 2bbl is the easiest carb to build, just set your float level properly and make sure you check the throttle plate for wear, have it rebushed if needed.

interesting that page 3 describes my problem of gas over flow on turns to where the car floods is an indication of float level set to high.

also im wondering after looking here - http://www.carburetor.ca/carbs/catal...y8-1961-76.htm if sense there are two kits ck90 and ck92 for a 2GV if he assumed wrong and used a ck90 kit when my carb, 7042834, calls for a ck90 kit!

i don't know enough about it but maybe all the parts work in either as far as fitting in place but its some variable like the size of a needle, seat, jet, or different gaskets etc that makes the difference and he just used the wrong kit,... twice!

if anyone has the "C" section of Parts and Service Manual as mentioned on page 18 of the service manual, from the link i posted, i would highly appreciate it! (i tried the contact email on the page but it bounced back. )
