I have a '91 Carat on which I just had installed new heads, head gaskets,
etc.  WHle I was driving yesterday, one of the valve adjuster screws backed
out and fell out of the arm.  When I got home and diagnosed the problem, I
found that the screw threads were damaged beyond use.  No problem, I pulled
another screw from an old 2.1 and tried to screw it in the arm.  The threads
in the arm were damaged too.  No problem, I just pulled the rocker arm
assembly off the old 2.1 and installed it on the Carat engine.  Now the fun
begins.  This happened to the head on the right side of the engine - cyls 1 &
2.  I have set the distributor to show #1 at TDC and after figeting with the
push rods to get them to fully seat, have gotten the valves adjusted on #1
(the adjusting screw touching the valve stem plus two full turns clockwise).  
My problem comes when I try to do #2.  The way I figure it, if i turn the
engine backwards 180 ddegrees, both valves should be closed.  The mark on the
pulley shows that I am at the right spot and the end of the rotor on the
distributor is 180 degrees from the mark on the edge, but it appears that the
exhaust valve is still open.  The push rod won't seat as far as the others
did and the adjusting screw is out all the way and there is no play between
it and the valve stem.  What gives?  I wanted to go to my son's ballgame
today but this is standing in the way big time.
