Is there a switch on pressure washer to prevent getting fire to the spark plug other than the obvious on/off switch?

SOURCE: Honda Pressure Washer HP 5 not starting

You can try spraying some carburetor cleaner into the carb. If it starts for a minute, your carburetor need cleaning. When you added new gas did you remove the old gas first? Is the air filter clean?

SOURCE: pressure washer shuts down after about 15 sec. of

It sounds like the little engine has an automatic choke that is not functioning properly. If not that, then the linkage on the manual choke is maladjusted such that it is keeping the rich/lean mix out of whack. If you find it neither of these, then you are down to the governer. Remove the breather and watch the carb closely as you pull the trigger. You should see a linkage arm with a spring attached to it. Sometimes that spring comes off causing the governer to stop governing. I'm not really a small engine expert, so if one comes along, I shall definitely defer.

I have a ryobi pressure washer with the honda gcv 190 and it wont start i got fuel and spark and the switch is on it just dont want to start

Is this a brand new unit or one that you've had awhile? If one you've owned awhile, when is the last time you used it? Did you use a fuel stabilizer or drain the tank and let the engine run until it stalled?

One thing you might try would be to remove the spark plug and give a little spray of carb cleaner in to the plug hole, then reinstall the plug and try to start it. If there's just not enough vacuum to get fuel to the cylinder, getting the engine to fire off the cleaner may provide enough oomph to get the engine started and running.

My Mi-T-M 2600 pressure washer will not start, how do I clean the air filters and get a spark from the spark plug.

If you take out the plug check the tip for fouling - that will prevent it from firing properly. Testing for spark can be a pain -easier to just throw in a replacement plug and see what happens.

Did you remember to prime unit and set the choke on startup?
Try some starter fluid - if you get any sort of firing or miss you know you have spark.

How does the on/off switch operate the washer?

On/off switch shortens the ignition coil to the engine body and thus stops the spark plug from firing.

My pressure washer doesnt seem to run properly. i have changed the fuel,air filter,spark plug and the oil. It will start but runs poorly.

Ok the first thing you need to check is if the spark is fireing. To do this you need to remove the plug plug it into the spark plug cap hold it on the cylinder head pull the engine over it will pull easy and see if you have a blueish spark jumping the gap on the plug . If you do its not an electrical prolbem . Then put the plug back and plug the ignition wire back and remove the air cleaner see if it will start then .witch the choke on . If it still won't start try pouring a small amount of fuel derictly into the carbuator if it runs for any time at all or even starts to fire then its a fuel issue eighter bad fuel or clogged filter or carbuator needs to be cleaned. You can even put a small amuont of fuel right into the spark plug hole then put the plug back in and it should start You need spark fuel and air for any engine to run if you have all three its automatic it will at least fire Good luckwith this

Does not start. what could be the problem?

Make sure the oil level is right. Check for spark by removing sparkplug and reattach the plug wire on it and ground the nut part of the sparkplug on metal on the engine. Whith the switch switch to on you should see a spark between the gap of the sparkplug when you pull the cord. If not get a new plug and make sure it is gapped to 30 thousands. If you are getting spark put the plug back in and tighten and reconnect the wire. Take the air cleaner off and put a spoon full of gasoline in the carburetor and pull the cord. If it fires for a second the carburetor has to be taken apart and cleaned.

I have a rough time cranking my power washer, I go through the proper procedures but it will not start. It act like it want to crank sometime, It also backfire. How could I troubleshoot it.

Hi and welcome to FixYa, I am Kelly.
Back firing can be caused by 2 things... A spark plug / ignition breakdown or.. a sticking engine valve. Before you do anything change the spark plug. ( BPR5ES ) or equivalent. A bad spark plug will still arc at the cylinder head from the outside of electrode to the cooling fins but will not jump across the inside of electrode when installed.
If the unit has been in service for a few years the valve seats tend to get carbon on them and makes it really difficult to get it started. A single backfire can cause it not to start for hours as the backfire loosens carbon in the cylinder head area and prevents the valve from seating; therefor you lose compression. You can sometimes get by with just carb cleaner straight into the cylinder head.. but most of the time you have to remove the cylinder head and hand lap the valves with valve grinding compound. The exhaust valve is most always the culprit.
Most pressure washers do not have an oil level safety switch but if there is one installed these buggers can and do cause havoc when the sensors are dirty (wash with gas then carb cleaner) or the oil is low.

Thanks for choosing FixYa,

My troy built 2200 pressure washer was running fine but then shut off instantly I then noticed it had low oil I filled it but now it won't start

Pressure washer takes oil in two places:
Pump oil is 20-30 weight SAE non detergent and comes half way up/ do not fill more than 1/2 way
Engine oil is 10W30 and comes half way up dip stick
IF you overfilled the oil >>> DO NOT turn power washer on it's side or upside down to drain oil >>> because engine oil will fill carburetor

When engine won't start
We pull off air filter so we have direct access to carburetor
Spray WD-40 into carburetor while starting
The engine will fire on the WD-40

You can keep spraying WD-40 into carburetor to keep engine running while moving choke to see if engine will run on it's own
Squeeze gun trigger so water comes out gun and pump pressure doesn't stop engine

If engine will not fire on WD-40
Spark is suspect
Your spark plug gets power from ignition coil
If coil is bad you get no spark > and coil needs needs replacement
Take out spark plug, clean it with WD-40 and use a bit of sandpaper in the spark gap
Put spark wire back on plug
Touch threads of spark plug to metal part of engine > pull cord and look for sparking between spark plug and engine
If you do NOT have any sparking, then coil is bad
If you HAVE spark, then your spark plug needs cleaning or replacement

If engine fires on WD-40 but will not keep running
Then either fuel or carburetor are suspect
Loosen hex nut on fuel filter located below gas tank >> if fuel flows, then re-tighten hex
Next, pull off rubber hose connected to carburetor to see if fuel flows to carburetor
If fuel is flowing to carburetor, then the carburetor is suspect.
Small engine repair shop will have carburetor cleaners

Check exhaust
There is a screen over exhaust
Make sure it is clean of carbon build-up > Use WD-40

Change air filter

Won't start, small engine guy said carburator needed to be flushe

Hi lackeyapda:
Fire Air Fuel

Remove the spark plug, plug it back into its wire. Hold it close to the metal frame WITH INSULATED PLIERS. Pull the cord and see if you get a spark. If no it is the coil, plug wire or a safety switch. If yes
put it back together. Take the air filter off. Spray some "easy start" or "carb cleaner " into the carburetor. Try starting. If it starts for a moment then dies, you do need to clean your carb.
