SU HS Carburetor Needle
       Searchable Selection Chart

       Finding SU (Skinner Union) needles to make your car run right under all throttle conditions is a trying experience at best. This page should help a bit. HTML and Perl have been used to develop this database driven charting and searching tool. I wish I could make it a bit easier to use, but this will have to do for now.

   How to use this chart 

         Grab a piece of paper and a pen or pencil, and the number (letters) stamped on the carburator needles you already have.  By entering the identification in the code box (not the  AUC part number but the ident. stamped on the needle)  and pressing the search button, the database will return the values (diameters) of each of the 'stations' for that SU needle. Write these down.

        Now you can go back in and fill in one, or as many as you like, station diameters and the database will return all the needles within that range. Remember, smaller diameters, mean the needle is richer at that station.

       I've found it best to simply enter 2 or 3 stations at a time to search. Once you play with it a bit, you'll get the hang of it.

update...here's the latest attempt to present a web based searchable
needle index. This is a totally stand alone javascript based 0.090" search
table. The page may say the script is running slowly and ask if you want to
continue. If so, click YES, and it will run properly and at full speed without problems.
(It's a bug i nthe difference in Sun And MS versions of Java) . It'll work just fine.
You can seach by station to compare what other needle is near that one.
