SU lifting pin

["Nathan Ruffcorn" <nruff@famvid.com>]

I hope everyone is having a great weekend.  I just got my carbs back from
Z-therapy.  They look and feel great!  I was reading up on several SU tuning
FAC's and found some conflicting info-hoping someone could help steer me in
the right direction:

1.  How high do you raise piston to check for lean/rich mixture.  One FAC
said 1/16" the other said 1/2".  My Z-therapy carbs are sans lifting pins.

2.  When I raise the piston and find a lean/rich mixture, do I adjust the
mixture on THAT carb or on the OTHER carb?

Thanks in advance for all your help!  I know that adjusting SU carbs is
"easy" and I'm slowly learning.

Thanks!
Nathan
