GC190 flooding

[ggenovez]

HI everyone,

I picked up a Kracher pressure washer a few years ago. It's been running fine until a few weeks ago. I noticed that as I would crank, gas would come out of the exhaust. I took apart the carburetor and cleaned the carburetor on Saturday. Ran fine for that day. TOday I asked my son to powerwash something and he couldn't get it running. Sprayed some carb cleaner and she started a little rough but ran for about a minute and I turned it off. Ran off to do some errands and now she's not running anymore. I took the plug off and it was soaked. Got a nice spark on the block. So I opened the carb drain valve and dumped some of the fuel, and she started and ran for about 10 seconds and then flooded again.

Any ideas?

Equipment numbers needs posting...

But for now it sounds like you a leaky needle and seat assembly in the carburetor or simply a float that hung in the open position. Carburetors should be ultrasonically to clean them properly. When you have fuel coming out the exhaust you most likely have fuel in the oil too which is usually indicated by unusually high oil levels. This needs to be change as oil is contaminated. Fuel can fill the cylinder to a point where you can not crank the engine through a complete cycle which is a hydro-lock condition.

One note the use anything other the regular fuel to start the engine is not normally good the engine as it washes away the cylinder lubricating oils.

Honda's generally have filters in the tank outlet, but it wouldn't hurt to flush the tank and clean that filter, in addition to what Starfire said. Also, check the float to see if it has gas in it, making it too heavy to float properly and close off on the seat.
You need to post the equipment numbers.

What we need for the engine is the model number, type number and the serial number for part references the engine family number won't help us. Here a link to how to find your engine numbers.

Engine model is a GC190

GCAAA - 1180710 QHAD

Starfire1, you were right. The oil was full of gas. I've taken the carburetor apart (again) and ultrasolicaly cleaned it, and I can see the float and needle functioning but it's still flooding. Any other ideas?

Thanks!

If this is the right GC190...you can get a whole new carb for $20 plus s&h...

Or use the one you have and add a fuel cutoff and chance forgetting to shut it off.......like I do.

Operating needle by moving up and down is not necessary means it is sealing. With carburetor inverted apply fuel to it through the normal fuel line connection. This should tell you if the needle and seat are sealing properly. I suspect it not sealing. The float should be level or slight above level with the carburetor base when carburetor is inverted and it also should not contain any fuel.

Also when replacing the bowl while the carburetor is off invert it before putting the bowl on. I have seen a few carburetors where the float got jammed open when done in the normal position.

Although it is for a different type number engine (QEAF instead the QHAD) the carburetor is the same number. PN 16100-Z1A-802

A new needle would not resolve my issue? I need a new carburetor ?

Thanks
