New Karcher pressure washer won't start

Carburetor float is stuck and flooding the engine.
Replace the carb.
STEP BY STEP HONDA GCV 160 CARBURETOR CLEANING THE CORRECT WAY

If you left the gas setting in the carb your carburetor may be gummed up drain the gas put new gas in and removevair filter ur just a little gas down the carb. And see if will start if it does pour a little mechanic in a bottle in the gas tank that will clean out the system.

It sounds like the carborator has a drain ****, with a hose attached so it doesn't get gas all over everything. The reason to do this is to drain condensate once in a while. See if you can find a small drain valve and check to see if it is closed. Then add some more gas and wash away!

Hi Gary,
Looking at your owners manual I see this is a Honda GCV 160 engine. (owners manual)

Download this carb check sheet and follow the steps:

You have debris in the main orfice jet or tube. These are removed from the threaded area of the float bowl nut with a screwdriver that fits EXACTLY into the brass slots of the orifice and after orifice removal the main fuel tube. IF you damage these during removal i..e you use the wrong screwdriver or damage the thread slots you can end up having to change the carb. Just make sure the screw driver engages the orifice and fuel tube slots fully.

After cleaning the main fuel orifice and fuel tube check fuel flow into he float bowl. It should fill a spray paint can lid in around 10 seconds. If you do not have this kind of fuel flow.. investigate from the float needle back to the fuel tank outlet for restricions.

Make sure the governor linkage is clean and works freely. A lot of times when you put a load on the machine, use it it stopps the fluttering.

This is a relatively easy SELF correction process. Mind you a pool is FRESH water.

1. Drain all gas by remove the hose that connects to carb and completly drain the gas tank. (If there is an in line fuel filter or glass debris bowl, change filter / empty bowl.
2. Remove float bowl nut and bowl and purge water. Spray carb with carb cleaner while float bowl is removed. Paying particular attention to the float bowl nut thread area (throat)
3. Drain Oil. AFTER step 5.
4. Pressure Pump oil should be fine as it is not vented. (depending on pump installed but none of them are vented.
5. Remove spark plug and put about 1 ounce gas directly into the cylinder IGN OFF! Pull recoil and let gas exit spark plug hole. Reinstall a NEW spark plug BPR5ES or similar
6. Service engine oil
7. Fan dry the unit over night. Simple floor fan will do. Leave the gas cap OFF / float bowl open overnight during Fan Air dry.
8. Next morning service gas tank
9. Select fuel on and let a small amout of gas leak before installing the float bowl and nut making sure the float bowl gsket is installed against the top of the float bowl.

Final testing time... Ign. on.. Test spark first. Spark check good. FUEL ON. Start.

Just make sure to change oil again in 10 hours. Water in oil will cause the oil to appear milky.

You can do this. Worst case the electronic ignition module fails. (They are cheap... !) Most of the time the coil will not need to be changed.

That is water de-contamination 101 and you just completed the course. Give it your best shot. It beats buying a new one and yes it is worth repairing.

P.S. Oil the TIRE / WHEEL bearings.

Karcher Model G2650 OH with Honda 6.0 HP, GC 190 Engine. Engine won't start. New gas, has spark. Seems to flood instantly. Much gas in cylinder. Spark plug wet. Choke pulled out, power on. Oil OK. released pressure in line. Where can I down load a Honda Engine manual! Thank you !

did you pour all of the old gas out before you started to use it. Sometimes condensation builds up in gas tank when stored. You need to dump old gas an put in new gas.

I have a 5hp honda power washer sat for 2 years it will only run if I spray gas in the carb as soon as I stop spraying the engine stops I have took off carb and cleaned it

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.
Regards,
MG.
