  Do you end up changing it or it checks out as correct?  If you 
changed it more than one time in several rechecks, you're doing 
something wrong.  It won't change and should repeat, repeat, 
repeat within .05mm due to line of sight error only.
  Once you've set the cam, omit loosening and setting the cam 
timing anymore, it can't change relative to TDC (enough to matter 
anyway.)  Belt tension won't change either so don't muck with it 
after it's set either.
  With those done, rechecking your timing is simple.  Turn the engine
to TDC #1.  Look in the oili filler hole to make sure lobes are up not 
down (#1 instead of #4).  Remove the bolt and screw in your gauge.
Make sure not only that your cold start knob is pushed in but that you 
check behind the pump and make sure the lever it operates is against 
its stop.  Adjust if necessary.  Turn your gauge's dial to read zero, 
just as a reference, be sure the counter needle is above one so it 
won't "bottom out" as you back it up.  Turn the engine counter-clockwise 
(facing the pulley end) until your gauge has JUST stopped moving, 
don't go much more than that.  See what it reads for curiosity's sake, 
set the face to zero on the needle then turn clockwise to 1.02mm.  
Yeah, it sets to 1.00mm.  Move pump if necessary.  Tighten pump.
  Repeat from turning counter-clockwise on and see if results repeat.  
They should.
   Honestly it sounds more like air in the fuel line, supply or return.
