My pressure washer is like new cond with little use and I got it for $45, It has the original air filter and oil and both are clean! It has worked great last year, However today I lost pressure after using it for 2 min today and unless the hydrolic oil is bad,, it may go in a mini bike. The shaft is 5/8" the engine ( 160CC) is a little tall and the exhuast is up front but it would still work out. I still would like to use it but ain't going to spend more than I got into it on a pump! The fluid looks good (just slightly dirty) and is showing in the window so what the hell? Help?
