If it didnt move your mech advance was already
in (advanced)... it will move if the mech is
still retarted.. this is FACT
EDIT
By the way.. I bought my dist machine out of
the dist lab at Chrysler.. where I worked for
1 year before I moved to the fuel lab.. I did
this test a lot and magically it moved each time
unless it was already advanced.. but the nice
thing about using a dist machine is you can start
out at zero rpm and work up to 4000 (dist rpm)to
see the total advancement on the mech.. then apply
the vac for total
