It may be a simple repair, but not always easy to recognize the
symptoms. In this case it was a shuddering as the car was brought
to a stop. Our long time mechanic, who had worked on the Volvo
many times, thought it was the brakes, and replaced almost the
whole system. His partner was a better mechanic, who was one of
those rare individuals that knew how to tune the dual carbs on
our Volvo. Unfortunately, he was no longer around when we brought
the car in for diagnosis.
This 75 year old Swede must know something as his lot was full of
newer Volvos. He just didn't want to be bothered to chase down a
replacement unit, and instead threw in an untested replacement
lying around his shop that did not work.
I still think Volvo should do a better job of keeping records on
their parts installed. Remember, a Volvo is 'For Life', which
may work if you die an untimely early death. I'm not bitter, just
more cautious about what they tell me.
