My first thought would be the screw that holds the carb bowl. It has a little orifice and 4 holes evenly spaced around the base of the screw and it is vital that all holes and orifices are completely free of gunk and trash or varnished gummed up stuff. That must be cleaned. I use B-12 Chemtool carb jet spray. I suggest using compressed air as well. An old guitar string (G,B,or E strings) works well but do not make sharp bends with the wire! It will snap off at the right time and poke your finger. This case calls for a little common knowledge Lol. And supposing the main jet has been sprayed and blown out. Main jet is the tube with many evenly spaced holes around it. Some are removable. I clean my carbs using a welders torch tip cleaner files. Never ever ever force a wire too large in these orifices and holes. Always use the nxt smaller size wire.

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.

you should have an air/fuel mixture screw on the carb somewhere. Start the engine and turn it one way then the other a small amount at a time. One way it will get worse and one way it will get better. Keep turning till it smooths out

Check the level of the fuel in the float chamber, it could be low.
You can also check the solenoid valve ....turn the ignition 'on' and you should hear a click sound at the s/valve, this proves the valve to be openning ones the ignition is turned 'on'.
Hope this helps!

Most carbs have a H (running) and L (idle) mixture screws on them, but the newer ones are getting away from that somehwhat and some aren't adjustable. I am including a tech guide for carb adjustment for a Zama carb. All diaghram carbs are similar.

Check the amount of fuel running from the connector line at the carburetor--it should run out as thin stream. If it just drips, the fuel filter ( a fine brass screen just above the bowl at the shut off valve) may be plugged. If ok, then remove the float bowl, the main jet, and the emulsion tube that runs from the rear of the jet out to the venturi in the center of the carburetor throat. Look for a short brass tube sticking into the venturi--use the flat of a screwdriver to gently press down on that short projection to drive the tube out of the bottom. Soak this tube and the jet in carb cleaner--make sure all holes are clear. Don't use wire or needles to poke into the holes--use toothpicks or other softer materials. Hope this gets you running again!
