Question about Karcher 2500 PSI Pressure Washer
I have cleaned the carburator. There is gas to the carburator. I used a starter fuild to check for air leaks. I did not find a leak. I am concerned that the fuel line filter in the gas tank is blocked. Any ideas

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.

pour a bottle of carburettor or fuel injector cleaner in the fuel tank, replace the spark plug and set the spark pluglug gap at 0.7mm. Replace the air filter element. Also change engine oil if necessary (mobil 10w30 synthetic.

SOURCE: engine won't turn over
Pull the spark plug back out and try to turn the engine over. If it doesn't move then the engine is probable seized. Was the engine oil res. full of oil and was the color acceptable.

Lets back up and regroup on the carb cleaning.
Before you start.... if you have a digital camera take "close up" PICTURES of the linkages and springs attaching to the carb. If this is your first time you will be so glad you did. You can always delete them later if you don't need them. :)
Here is what you need to do:
1. Fuel selector off
2. Remove float bowl mounting screws and nut
3. Remove the BRASS Jet / Orifice in the very bottom of the venturi tube inside the pickup tube. (Flat blade screwdriver) Hold the Orifice up to the light. You should see a pinhole. If it is not clear clean the orifice but do not force anything through the hole.
4. Underneath the Orifice there is yet another BRASS tube that you need to remove. (Flat blade screwdriver) Make sure all of the holes in the tube are clear. The tube will be over 2 inches long. Clean it and reinstall it.
5. Reinstall the Orifice.
6. Using a catch fuel container turn on the fuel selector. Fuel should flow at a good rate. GENTLY lift the float assy level and make sure fuel flow shuts off. When you drop the float again fuel should flow.
If you do not have fuel flow at this point the needle and seat will need to be inspected. Fuel selector OFF.
(The following procedure is to be done only if there is no fuel flow with fuel selector on.)
a. Remove the silver float pivot pin retaining screw
b. Drop the Float down (The needle will come off with the float. NOTE the position)
c. Inspect the tapered rubber of the needle If should be pointed. If it is not pointed then the rubber tip is stuck inside the seat.
d. Clean the seat hole ONLY if obstructed. (Easily damaged)
e. FUEL Selector on then off fuel should rapidly flow through the needle seat.
f. Renistall Float and needle making sure to get the pivot / hinge pin installed correctly and reinstall the silver retaining screw.
g. Fuel selector ON. Raise and lower float checking for free movement with fuel flow when lowered and stopped when the float is raised level.
NOTE if fuel does NOT stop when float is level you will need to bend the float tab (tab up if level is too high or tab down if level is too low) where the needle attaches to the float assy until it does.
7. If there still is no fuel flow at this point remove the fuel hose from the carb and check fuel flow. If no flow check that gas tank exit hole, fuel filter (if installed) and the selector valve assy for obstructions.
FUEL FLOW IS GOOD
Step 8 is VERY important"
8. BEFORE you install the float bowl inspect the bowl nut. There are 2 holes in the side of the nut where it screws in to the bottom of the carb that must be clear.
9. Install Float bowl mounting screws and nut. Check for leaks.
10. Test engine.
That should do it.
Thanks for using FixYa.
Final note... if it does NOT start after this there are other problems we can discuss. i.e compression and spark "how to."
