Question about Karcher 2500 PSI Pressure Washer
I have a Karcher G 3000 BH pressure washer with the Honda GC190 6.0 HP engine. The engine starts and idols fine, but when using the pressure washer, the engine seems to surge. It will surge between working fine with high pressure to low idle and low pressure. Any ideas where to start?
This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.
