SU needles part two, the modification.

[Keith0alan@aol.com]

Hello all,
   Spent the afternoon starting my first attempt at modifying SU needles.
Using the oxy box, needle (rat tail) files, rulers etc. I am trying to level
out the fuel air mixture curve.  While the going is very slow I seem to be
making progress. I am going to order another set of these needles (M-43) so
that I can compare between original and modified. 
    With any luck I will be able to come up with fairly simple methods to
improve the stock needles.
