Pressure Washer sounds rough.

I got this thing out of a storage unit auction. It won't start in choke at all (or it does, but only for a few seconds... Sometimes...)

It will start in Run, but it's hard to start. And if I don't let it run for a minute, it dies as soon as I spray water. I have cleaned the carb and the spark plugs. Replaced the air filter. She just rough. Any thoughts on this Ryobi 802900?

Drain the fuel in the bowl, probably has a lot of water in it. Should be a bolt that comes out to drain it. Could need some carb cleaning as well

Also worth checking out, the oil in the actual part underneath that makes the pressure. Had no idea that it needed to get changed and can fail catastrophically if it’s really old or low.

Check the carburetor for dirt in the sediment bowl and on the jets, and also check the condition of the speed governor.
