RYOBI 25cc petrol strimmer begun to create unacceptable vibrations.
My 'RYOBI25cc petrol strimmer has begun to create vibrations through the handholds. The engine seems to be running ok, and I continued using it ok. Apart from ending up with unacceptable buzzing and humming in my hands afterwards. Is there an adjustment to the way the engine runs to prevent excessive vibration? Any ideas gratefully received.
