My AVS numbers, was: Carburetor Problem

[dardal@xxxxxxxxxxxxxxx]

All you guys with the books, here is the info.  My AVS from the front it says 
K496BS or K4966S (can't tell for sure, the letters are not defined very well).  
Again, this is at the lower flange face in the front of the carb, towards 
passenger side.  On the left side (driver side) it says 2046 and on top of the 
carb it says 2020.  I don't know what these numbers mean, but the first one 
must be its part number (guess).

So, can anyone identify this AVS (I am quite certain its an AVS, but I have 
been wrong before) and most important, tell me its advertised capacity in CFM?  
>From the looks of it I would guess about 600 cfm.  It is spreadbore, and I 
think the bore size is 1.44" and 1.69".

Thanx 

D^2, 2x68
