Stomberg Carb Problem

["David Schenck" <David_Schenck@msn.com>]

I have a 1978 Spitfire with the Stromberg carb on it.  My problem is that it 
runs way to rich.  I have tried many things including putting on another carb. 
 They both however are old and possibly worn.  I am looking for suggestions on 
what I can do.  About the only thing I haven't done is to replace the 
needle(s) and I am not sure which one(s) I need.  Any help would be greatly 
apreciated.
Thanks
