Small Engines (Lawn Mowers, etc.): gc160-gc190 karcher pressure washer, karcher pressure washer, carburator

Question
it has begun to idle really rough and die out - already swapped spark plug, then same symptoms
I read somewhere it may at idle have too Much Pressure for the Engine to Handle

Answer
Mr Salva,

   Pressue is the key trigger for any pressure washer try lowering the pressure at idle speed and see if that helps mellow out the engine If not have the carburator rebuilt sometimes event best maintained engines need a rebuild to keep it performing at top standards
