Trying to set the unloader. 4gpm 4000psi. Honda gx390. Using the green tip, gun on, started engine throttled about 75%, no water exiting bypass hose, turned the knob all the way down and all the way up still nothing, can’t get the trickle. Do I need to pop the knob off and tweek the nuts around the spring?

Why did you throttle it down?
Not sure, is it ok to run full throttle? Is it anything like flooring the gas pedal in a vehicle?
It’s supposed to be left on full and leave it alone. The engine has a governor that prevents engine damage.
Good to know, I’ll try setting at full throttle, thank you
I always start up and shut off my engine around 1/3 throttle or so… but it runs wide open while working.
