Hi, it's me (Margie) again.  I have another question.  What kinds of
problems do you experience if your cat is clogged?  Is it difficult to
gut a cat, or is that considered inappropriate (or rather;  Just not
nice for people who appreciate clean air)?  Our van has not been running
to good after we got it out of the shop.  If you don't remember they
told us our dual carburetors need to be rebuilt and maybe even
replaced.  When we were driving it home there was white smoke (not a
lot) coming out of the tail pipe (and there was not smoke before we took
it in).  A friend told us they might have made it run richer to make it
run smoother.  They also tightened up the throttle spring so it's hard
to press on the gas.  The idle sometimes is  real smooth and steady, but
after driving it for awhile when you come to a stop you have to press on
the gas to get it not to die.  It's also started spitting stuff out of
the tail pipe(thus the cat question).  Any ideas?  Any suggestions and
advice would help and be much appreciated.
oh....one more thing...I was closing the passenger door and the window
fell into the door.  The window will roll down but not up. We took the
door panel off and have the Haynes book with a window diagram, but we
are still having trouble figuring out why it won't roll up.
Thanks for all your help!!
