Sorry - couldn't resist.
It might be worthwhile to see who did what to the motor so you can
eliminate possible trouble spots. For example, maybe the motor got rings
and a valve job, but they just stuck the old rocker shaft back on.
It's pretty easy to miss important steps in a rebuild and keep the cost
down.
However, if the rebuild was done professionally, there should be some
documentation on what was done and what parts were used. If not - well,
you gotta make some guesses about what was done.
The broken valve spring can be from over-revving, but it could also be due
to the valve "hanging" in the guide. It can also be due to excessive cam
lift - is there a "cam" in this thing (meaning a high-lift non-stock cam)?
I'd go for a valve job and really check the rocker shaft. Then I'd look
into coil binding on the valve springs.
