Got a Subaru EA190V power washer S/N EA190-1479542

Lent it to a neighbor and was working fine.

Got it back, started her up and noticed fuel shutoff was closed. So shut engine down and turned it back on. As soon as I turned fuel shutoff on, gas started pouring out of carburetor. Seems like there is a gravity open stuck somewhere...

Neighbor stated this happened to him too, but let engine cool down and problem went away.

Any help in troubleshooting order of things to check before pulling apart would be appreciated.

Thank you

Did some more research and found it could be the float needle valve stuck. Would that be the 1st thing to look at?

yep float needle failed most likely.

Yeah

Is there a chance the needle valve is just stuck open and bowl float & needle valve just needs to be cleaned out? I found the carb assembly item 210 in the diagram for $68 on ProPartsDirect so that seems a little more reasonable. :unsure:

Thx!

That is very possible, that's what I would do since the alternative is somewhat expensive.

Drained bowl. You could see gas mix in bowl was like dark turpentine, but bowl much cleaner than was expecting. Valve was stuck, so used carb cleaner and compressed air and got it moving again. Cleaned the bowl and then gave it a go. Started right up.

Thanks!

What do you guys recommend for pressure washer pump protector?

My pump does not have an oil resevoir like some do.

The $15 bottle you can get at HD seems like a scam.

Thx

Are you trying to protect the pump during the off season? If so, I first, will suck through RV antifreeze to protect the pump from freezing, then turn off the fuel shut off valve and run the motor until it stalls. Put gas treatment in remaining gas in tank.
