  Depends on how much wear you have in the bore.  Most of the ones
I've
gotten into (around here) needed a rebore.  I suspect Mt. St. Helen's
ash
fits into the reason.
  Gains are less blowby, technically a quieter engine (HA!) better
compression
thus better starting, cleaner burning, less oil usage, longer ring
life...

so..if i can afford it ,a bore and new pistons will possibly add to
the life over just
the re-ringing?
do i always need new pistons if block is board?

thanks..
