I have a Craftsman pressure washer with a Briggs engine and run the **** out of it.
All of my power equipment have Briggs engines, and I have never had a failure.
Maintenance is the key to anything lasting, and this especially applies to small engines.
shotgunner11, Briggs and Stratton engines are used in all sorts of applications, and they are NOT primarily made for lawnmowers. They are prevelent on lawnmowers because of their low cost, low maintenance requirements, availability of parts, and reliability. I have worked on small engines for a very long time, and I prefer them because of the above mentioned reasons. I also like Honda, Kohler, and Kawasaki small engines in that order.
Also, for info, two of my firetrucks (brush rigs) have 20 horse twin Briggs and Stratton engines running their pumps. They have yet to fail, and one of them is over 15 years old.
