[Healeys] Syncro problem

I have rebuilt a 3000 side shifter gearbox that was in a very good condition.
I renewed all bearings and the syncro rings. All gears were very good with
virtually no wear at all. When I first test drove the car everything worked
very well. Gradually the syncro on 2nd gear stopped working, when down
shifting from 3rd gear, until there was no syncro action at all. The strange
thing is that the syncro on 2nd gear works fine when up shifting from 1st.
Syncro on 3rd and 4th work fine. I have taken the box apart and changed
everything that has to do with 2nd gear. Syncro ring, 1:st gear assembly, 2nd
gear, 1st / 2nd selector fork and selector shaft. The problem stays the same
with very good syncro between 1st and 2nd and no syncro when down shifting
from 3rd to 2nd. I would be very thankful for any advise leading to the
solution of this problem as it4s kind of driving me mad at the moment.

TIA
