SU's

I did the 1/8" measure, let the bowls fill, and pulled the tops off. The
level is well below the 23mm mark I made on the bowls, so I am going to try
to tweak it a bit so that it does not run over. at this level, with the
choke pulled you can barely see gas down inside the nozzle orifice. If I
understand everyone's thoughts, I think I should easily see the gas with the
choke pulled. Someone asked if they should see the puddle of fuel without
pulling the choke. It seems to me the carbs would continually overflow if
the fuel level is this high.   
 
My car seems to get very lean at high speeds (above 80). If the float levels
are significantly low I am wondering if they would contribute to this?
 
Thanks
 
Jon

The 311s.org FAQ says 1/8-inch drill bit, but there's some further
discussion:

I am certain I have seen someone referring to using a specific drill bit
size to accurately set the float levels on 2000 SU's. My car has the newer
style plastic floats with the attached arm.

If anyone knows this or a specific trick it would be great. Trying to
subjectively determine when the arm contacts the pin is not very exact.

Thanks Jon
