[Spridgets] SU question for racer types...

[Lester]

That's next.  The floats have no way to adjust, they are made of plastic and
have a tab as part of the float to limit droop but no way to adjust when the
close.  The spacer I made was a metal flat washer of appropriate diameter.  It
allows the correct closing BUT now doesn't allow for enough space between the
needle and float so that there is restriction in flow coming in.

No fast idle screws even installed...  I had to grind the mounting tabs so
that they didn't hit the fast idle cam..
