Responsive preventative maintenance

I'm not sure that the subject accurately portrays the topic about which I'm
asking, but I couldn't arrive at a better term.

The person that flew the club airplane before me reported a magneto problem
in the squawk book. When I tried to start the plane the next day, I found
it unwilling to start. When the mechanic was finally able to get to it (a
day later), it turned out that the magneto used for starting had to be
rebuilt.

My thinking is that the report by the person that flew before me should have
triggered something. I'm not sure exactly what, though. Perhaps it
should go directly to the mechanic? Perhaps some third party should have
looked at it first?

An owner would do what in that case? I guess that's part of what I'm
asking. If you - as an owner - found a problem - and I'm guessing that
what the previous person saw was a lack of mag drop during run-up - what
would you do?

I guess it seems silly to me to wait for the next person before the plane is
actually "looked at". Would an owner wait for the next flight? That I was
there the next day is one thing. But what if the airplane was "off" for a
day or two? That would be the ideal time for the problem that's arisen to
be fixed. But that cannot happen if it waits for the next pilot.

[Of course, a separate issue is whether you'd fly it with no mag drop.]

What do other clubs do in this regard?

Thanks...
