Same here on my '87 Wes= ty.  Starting out in first gear has always been a challenge.  Last= time I changed the clutch, about 4 years ago, I had the flywheel trued and = thought that would cure the problem.  Not !  I do not remember wha= t clutch kit I put in there.  It does not, always, do it !  Seems = to get worse after long driving events, so I presume heat is causing somethi= ng in there to distort, either the flywheel or the pressure plate.  But= , again it has not worsened over the years and I have just leaned to put up = with it and let the clutch out so that the chattering does not get out of ha= nd.
