This is your tax dollars at work. I bought this powerwasher used from
the US military. I suspect that they wrote it off because the gas line
from the tank to the carburetor was rotten and leaking. Why else would
they write it off? If, say, the engine wore down and that was the
reason, the line would not be leaking. I replaced the line and the
engine started on the second pull. It is supposed to be a bad ass
power washer, up to 3,000 PSI, with the Briggs and Stratton 11 HP
Industrial/Commercial engine.

First Question: the engine goes faster and slower every 6 seconds or so,
maybe varying speed by 30%. Why would that be the case.

Second question: how would I regulate water pressure on this beast?
There is no obvious valve that I could touch. I think that 3,000 PSI
is serious pressure and I want to get some opinions before I start
messing with the pump. Maybe I should torque the nut on top of the
pump, shutting off bypass.

keep a distance from rubber parts and seals on hydraulic cylinders..
also radiators and anything else that 3000 lbs will shread. Get a good
rain suit until you learn how to point that thing.. Watch out for the
corners/
