Cleaning fouled spark plugs.

Some people say there is nothing in a spark plug to wear out.That might be true but they do eventually get covered in a layer that can short them out so that they don't spark.This gives a misfire at best or stops the engine at worst.These plugs I removed from my V8 engined P5b Rover. The choke mechanism was faulty and the engine was running on a mixture that was too rich.

 Using a combination of a solvent and oven cleaner it is possible to make the plugs almost as good as new.This avoids using a grit blaster (which most of us don't  have) and avoids any grit or sand being left behind to damage the engine.

No wire brushing or need for machinery and fancy chemicals. Details are on a spark plug cleaning page.
