Pressure Washer does not start ?

Buy a can of carb cleaner. Remove the bowl, and spray all the ports you can find. Check the gas in the tank. If it is gummed up, you need to remove it and clean the tank. It's all pretty easy as long as you have some mechanical inclination and can put stuff back together properly.

Just wanted to circle back with results after several tests.....

I sprayed carb cleaner directly into the air intake on the carburetor and again
attempted to start but only ran for a few seconds.

Removed bolt in the bowl and gasoline found that gas was flowing into the bowl.

Again sprayed carb cleaner directly into spark-plug cylinder then screwing in spark plug. Attempted to start, but engine ran for only a few seconds.

Removed air filter to expose Carb, exposing the float, which appears to be working fine, not sticking, and moving up & down as it should.

I then sprayed all the ports in the carb I could reach w/o actually removing the carb.you can find. Attempted to start, but engine ran for only a few seconds.

Next step will be to actually remove the carb, and put the entire carb in a can filled with SeaFoam and let sit overnight, then use a small wire to clean every hole in the carb, and maybe remove the jets.

Would like to hear additional feedback from Forum.

Does your owner's operation manual have a clause like this?

''NOTE: Periodically on the initial start-‐‐up or after the unit has been stored for a
long period of time, the float for your “Low Oil Shutdown” system will stick to the
bottom of the oil pan. Locate the two (2) wires to the Low Oil Sensor Diode (figure
“Low Oil Sensor Diode” to the right) located on the side of the engine block. Unplug
these wires and, only after ensuring the engine is full of oil, start the engine and
allow to run until warm (normally 20 minutes, as this will heat the oil and release
the float on the Low Oil Shutdown System). Then re-‐‐plug the wires to the terminals
on the Low Oil Shutdown Sending Unit.''

John....Great minds think alike !

I was thinking about the issue over-nite, and a light bulb popped and had the same thought "Unplug the low-oil sensor wires, then try to start'.
This may actually be the problem ???? Will try this solution and report back.
BTW, I don't have an Owner's Manual' with this unit, I bought a floor display and the store never provided.
Thanks again John M. !

There should be one online... if you google the model number.
This is how I find them for people that purchase items from us but have placed their manuals someplace and can no longer find them.

The carbs on these units tend to be limited throttle throw away that are usually so cheap to purchase new that no one bothers to do much more than the basics.

You can end up spending $50 in time and materials... not to mention travel costs... to fix something that can be replaced for $20.

It could be as simple as you need to top up the oil. Unplugging that sensor may not work if that is the problem.

John,

Disconnected the Low Oil Sensor Diode, and attempted to start, but no success. Engine didn't have any indication to start.
I know it's getting spark, because in previous attempts, after shooting starter spray into plug cylinder and in-take of carb, it did start for a few seconds before dying.

Only thing I haven't done yet, is remove entire Carb and soak in carb cleaner and inspects all ports and jets. More to come......

John Mercier · 08-14-2022, 03:39 PM

Pretty sure that your getting air and spark. Float bowl has fresh gas, so that would be the next step.

Though I do wonder if something got into the gas and is blocking the jet. If it is just ''gum'' then the soak should solve the problem.
