Hey all,
I recently received a pressure washer for free. The previous owner said it was left at his house after a job. I like tinkering around on motors, especially if I can get it running for a small price, so I took it to see what was up with it. I did a simple spark plug swap and got it running. After connecting a water source to it, it wasn't generating pressure. I ended up buying a new pump for it. Now it generates pressure, but when I pull the trigger the engine dies.
From my research Ive found that its the unloader valve, but the valve is also brand new with the pump. I have not gone through the carb or anything like that yet, but that is my next endeavor.
Now the pump that was intended for the pressure washer is no longer being built, but I went with another pump that was the "new replacement" for the model number. If I remember correctly, the pump is rated approx 200 PSI higher than the OEM pump. So if that could be the issue, Im thinking the unloader valve needs to be adjusted, if that's possible? Or I am also thinking I can swap the old unloader valve to the new pump?
Id just like to get everyone's ideas on it. The pump wasn't an expense I wasn't planning on making, but I think Im getting it close to running properly. Id rather not spend a lot more money on it... At that point Id might as well buy a new washer, haha.
