holley 770 problem

I was thinking it acts like the secondaries are comming on
and did the paper clip on the arm trick and it did not
move. I am pretty sure it is the main system not coming
in or to lean and maybe I need a 10.5 power valve instead
of the 6.5. I have been trying to get through to Holley and
the line seems to be busy all the time.
thanks,
