I have a BE pressure washer with a Comet AXD 2220 pump and a Honda GC160 5 HP engine. When using the washer the last time it didn't seem to be running like it did before. When running, there used to be a distinct difference in the sound between spraying and not spraying, like the pump unloads and the engine coasts then when you pulled the handle on the wand the engine sounded like it would load up. Now, it just sounds loaded all the time. I took the unloader valve apart and cleaned it all up and carefully reassembled it. The valve will load and unload the pump manually with the knob. Is the unloader valve the culprit here? Thanks in advance for the assistance.
