There are times when the blade is purposely put on backwards, like to
cut through vinyl siding on a house. It sort of melts it's way through
without cracking the old vinyl. The saw that only gets used 2 times a
year gets forgotten about and there you have it, a blade on backwards.
Not to mention that most or all new saw blades have the rotation marked
on it with arrows. Evidently some people need the arrows or they
wouldn't be there. Me? I manage quite well without the arrows but for
some people they change the blade, installing a used blade with the
arrows worn off, and oops. Sounds stupid, but some people simply don't
have the ability to look and understand mechanical things the way we do.
Doesn't apply to power tools like this, apparently, as others here have
Question: does it "roar" more than it did before? Do you remember how
noisy it use to be? Keep in mind that circular saws are generally noisy
If it seems about as loud as before, probably nothing wrong with the saw
itself. Either the blade is dull, or installed backwards (which would
certainly explain poor cutting).

If you mean their guarantee of satisfaction, not nearly as well as
they did when they were the biggest retailer on planet Earth. The
question is, did they quit honoring that warranty because they're no
longer the biggest, or are they no longer the biggest because they
quit honoring that warranty?
I don't believe Sears ever warranted power tools for life, just most
hand Craftsman tools, but excepted from that lifetime warranty are
Craftsman measuring tools (calipers, torque wrenches) and cutting
tools (saw blades, drill bits, router bits).
Could it be the motor brushes?
If the Sears part number is still legible, try Sears.com since they
have service information for quite a few of their products and other
