Small B&S engine piston seized up

I have a Briggs and Stratton high pressure washer that seized up during normal operation. Afterwards I could not turn the engine by pulling the cord, even after removing the spark plug. I disassembled the engine, and the problem is the friction between the piston and cylinder wall. I was able to knock the piston out of the cylinder with a piece of wood. I cannot see any cause for this high friction.

Can I save my engine by taking away the high friction between the cylinder wall and piston?

I would say it is best that you junk that engine and get another engine.

Hello sunnyflorida,

If you don't see a cause for this high friction how can you take it away ?

These engines are cheap enough, It really doesn't pay to go that deep into them. I'd go along with mowerdude and find a new replacement engine, Then you'd have a warranty and longer lasting machine.


Good Luck

I would still like to know what caused the engine to freeze. Did I do something wrong? The engine stopped suddenly without warning.

What are some of the common causes of extremely high piston friction?

Lack of oil would cause high friction. Have a good one. Geo

I go with geo,,lack of oil or this 10% gas caused a cylinder melt down,,,,you also may have gotten 15%. This fuel with the ethanol in it is not good for these little engines.
