  • Which Unloader valve?

    I FINALLY ordered the Honda GX690 engine for the jetter I am building. They are so backordered that I had to get the model with remote controls which I'll mount on the frame. Tomorrow I will be ordering the Udor 8 gpm/3500 psi belt drive pump. My main question is which type of unloader valve is best? Should I install an engine termination switch in case of overheating? Do I even have to install a water tank if I lower the throttle down for 6 gpm? Does anyone know a good source for pressure washer frames? Thanks.

      We install low water cut-out switches, thermal unloader and safety valves. The GX 690 comes with a low oil cut-out switch and an oil pressure switch. When you join in the low water switch, cut the black with yellow stripe wire at the back of the ignition box that goes into the 4 pin plug. This will cut the carby solenoid preventing the engine from backfiring!
