pressure washer 4000 psi honda image
eight_kind
I have a 13hp honda GX390 on my pressure washer. I use it commercially to make my living. It does the job, but my 4000 PSI 4 GPM pump will only put out about 2200psi. I have discovered (by adding a tachometer/hour meter) that the engine speed drops to about 2800 RPM when I pull the trigger. With the trigger released, the pressure on the gauge shows 4000 like it should, and the tach reads a little over 3600 rpm.
I discovered the governor is not opening up the throttle like it should. I can reach over and work the governor by hand and reach the speed I desire with the trigger pulled, which tells me something with the governor is not right.
I did notice it is missing the long skinny spring that runs between the governor arm and the carburetor, but I dont think thats the issue really. The governor DOES seem to kick the throttle wide open when the engine is off, but thats it. I'm confused. If it will do that, why wont it maintain engine speed under load?
I replaced the carburetor with a brand new one today with no change.
Help please!

that missing spring is the problem. Take the unit to the service center and have a new spring in stalled. It is your livelihood at risk. A couple of hours lost time should pay for the service time.

I have a cleaning business and pressure wash frequently. That sounds like a good price but make sure that the engine is Honda. I have two pressure washers and Honda will last forever. My 4000psi was 900 brand new. Good luck to you.
