You don't need a dial caliper, it is only a starting position, you fine tune
dynamically with the engine running.
Screw the jet up until it is flush with the bridge (note NOT as far up as it
will go) then screw down two full turns of the adjusting nut or screw.

Somewhere in the distant past I remember reading of setting the jet
level in SU's
using a dial caliper.
I don't remember how far down the jet should be set.
