not to pick on *you* directly, mainly i needed to put my opinion out there

there has NEVER been a reason to blow out the carbon on any engine. if it
is tuned right, it will never have any carbon to deal with! this is true
from the ancient in-the-block-valve technology of my lawnmower right up to
the I-VTEC technology of my honda. carbon is an symptom of a problem
elsewhere. mixture too rich, engine never up to operating temperature, etc.

oh yeah, since i brought up the briggs & stratton engine, ever notice the
spark plug on your mower just loaded with carbon? yes, they set them things
up at the factory to be extremely rich. how do you blow the carbon out of
it? :~)>
they are set rich so that they run cooler (ever notice your mower seems to
cut better when it is cold outside?) a lean briggs on a 95 degree (F) day
will melt in no time!

my wife would never buy the 'blow the carbon out' trick...
