    I was trying to clean out the cob webs and dirt. When the front came off the eletric wires that go from the switches onthe front to the eletric pump on the inside came unplugged. They are put together with male and female spade connectors. They are not color coded. So i cannot tell what wire goes to what wire.

SOURCE: % hp Honda Motor runs on choke

Dear LC39B,
Is it possible you are blaming the wrong part of the machine? Did you try the Honda Motor on its own? I am asking , because if the pump of the washer has some fault or a bit jammed, this will demand a lot of power from the Honda. You can try the Honda with no water connection and no gun.
Regarding the Honda motor, you should check the electrical system also. I am saying this because you did not mention it, in your service procedure.

manufacturer will provide wiring diagram if requested. If it's just the kill switch it doesn't matter-just put them on the switch. As long as you're not shorting them to ground, the wiring isn't crucial in a little motorised unit like this-that is: if you get it wrong, no harm but no go/ get it right and your going.

Motor in pressure washer not working. plug and cable okay.

Is it a Briggs engine? Is it a professional engine by Briggs? If so these engines have an auto choke system that is run off the thermostat off the exhaust that controls a tang that opens and closes the choke.

If its not working it may need adjusting. But more than likely you have either bad fuel or a restricted fuel jet. The jet is on the bottom of the carburetor bowl. Use a 1/2 inch socket or an off set wrench to remove the nut, it is brass so don;t go crazy, Also it has a felt bad washer called a sealing washer. If there is old gas in the fuel tank, go ahead and remove the fuel hose attached to the carburetor and drain it too. I have seen gas so old it looks like Vaseline! Wash out the carburetor bowl with a paper towel and check the small holes in the brass bowl nut because that is your jet. Clean it with carburetor cleaner, acetone, or a fine wire make sure it is clean..

reassemble the carburetor bowl and hand tighten the brass jet, again it is brass threading into aluminum so don;t go crazy. Also if you took the fuel line off go and put it back on, Try non ethanol gas and give it a try, Make sure you don;t disturb the carburetor bowl gasket .. Here is a pic to help ya

Honda Pressure Washer tilted on front - will not restart

If the machine has been tipped and oil has got into the combustion chamber then it will have gone through the carb first. There should be a couple of 10mm bolts on the bottom of the carb bowl, the lower central one holds the bowl on and the other is to drain it. I would suggest draining the carb, and also removing and emptying the small bowl under the fuel tap (also 10mm). Oil will probably have soaked the air filter too, and this will greatly restrict airflow into the engine so it will need replacing. If you have tried to start the engine you may have also pushed oil into the exhaust, but if it isn't too much it should burn off so don't be surprised if you get a fair bit of white/blue smoke for the first few minutes of running. If after draining the carb and checking/replacing air filter and possibly removing and emptying exhaust, the engine still doesn't start, it will probably be down to oil in the carb jet. This is easy to sort. First drain and remove the carb, then remove the bowl. If you look up the post that the bowl was attached to you will see a brass jet. This can be removed by unscrewing with a flat headed driver. It can be a bit fiddly to get out completely as it is a snug fit. There are two parts to the jet, a longer tube with small holes in the side and a main 'through' hole and the screw/nozzle that you removed. Clean through with brake cleaner, dry and refit. Before starting, check the oil level as the oil that was in the cylinder will have come from the sump and will need replenishing. Good luck.

I have a Clarke King 100 hot wash with a wiring problem please can you help with the 3 connections from the pressure switch ?

the pressure switch is so the burner goes off when you stop squeezing the gun, there are only 3 different combinations wire1 and wire 2, wire 1 and wire 3, wire 2 and wire 3, it does not matter which way you connect them. You will know when it is correct as the burner will only work when the gun is squeezed and water is coming out of the lance nozzle at high pressure.

My machine runs for a few minutes and then abruptly quits. It sounds like it's running out of gas, but it isn't. It has plenty of gas. I'm not a mechanic and don't have a clue what's...

Yes it could be the gas cap. Check the cap and see if there is a vent hole. Use air compressor and blow out the cap. If this is not working check the oil level, if your machine is equipped with a low oil sensor and your oil is low it will shut it down. If you look on the side of the engine block towards the bottom you will see a plastic housing with a wire coming off, this will be the oil sensor. Remove the wire and see if it will run, but make sure you check the oil before running if it's low add the proper oil check your owners manual. If the oil was low don't remove the wire try to run it. If it still won't run then remove wire and try because the sensor could be bad. It also could be a carburetor problem. If you try the steps above and it still won't run remove the carburetor and clean. Let me know how you make out.

The power electric was run over by mower -unit has no electical power

You could bring it to a repair shop where they will probably install a new power cord. The now-shortened power cord can be fitted with a new plug, and used as before instead - for a fraction of the cost.

From what I can tell, the pressure washer is a 120 volt type. Purchase a replacement plug - called a "cord cap". The most common configuration is pictured below:


A 15 amp / 125 volt male cord cap made by Leviton.

Your's is likely rated at 125V/ 15A (like the one above). This means there's 2 parallel blades and a ground pin - like most grounded plugs in your home. If unsure, bring the cut off section of the power cord to a hardware store to select an identical cord cap. You'll want to purchase the type of cord cap that has terminal screws - not the type without screws. The packaging of the cord cap will indicate how much of the cord jacket and individual wire insulation to remove. A little more or less won't make it impossible to do - but don't deviate too much from these dimensions for the best results. Once the cord has been stripped correctly - Disassemble the cord cap body from the outer shell by removing the screws on the front. Loosen or remove the 2 screws at the cord grip end and slip the shell over the end of the power cord.

Bring the cord cap body to the cord. The body will have 3 screws. One each silver (or light colored), bronze (or dark colored) and green. Loosen all the screws - do not completely remove them. Twist all the strands of each wire so that they are bundled together and there are no stray wires sticking out. Do this for each white, black and green wires. The black wire will connect to the bronze colored screw, the white wire to the silver screw and the green to the green colored screw. You can either insert the stripped wires into the small holes at the back of the terminal screws, or wrap them around the screw terminals themselves. The best way is to wire from the back - but if you choose to wrap around the screws, be sure all the small wires are under the screw head. Tighten the screws and tug the wires one at a time to make sure they are held firmly in place.

Once satisfied that the wires are connected correctly and tight - slide the outer shell towards the cord cap body. Align the screws with the holes in the outer shell. The parts will only fit together one way - so don't try to force it together. Tighten the screws in the front and then install / tighten the screws at the cord end to grip the cord. This clamp should be firm - but not to the point of crushing the cord. Test in a ground fault protected outlet and you're done!

I hope this helps.. please rate this reply - thanks!
