Honda 6hp pressure washer wont start

SOURCE: pressure washer wont idle and run

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.
Regards,
MG.

You need to remove the carb bowl, then with a small flat screwdriver remove the jet. ( on the side, at the bottom of stem.) take a small wire or toothpick and clean the gunk out of the jet, reassemble and open fuel valve, start, and pat yourself on your back.

Sounds like the carb is badly clogged internally. If you can remove it yourself, you can soak it overnight in a can of carb cleaner. But keep in mind some of the internal passageways in the carb are as fine a human hair and soaking may not work, it which case go to plan B, new carb. Last resort you could try to find cleaners small enough to get in the passageways of the carb, I've heard of people using wire brush bristles for example. Today's gas is terrible, it does not take long to gum up the carb, if it sits for any time.

Testimonial: "you nailed it..........shitty fuel and clogged main jet..........lets see if it still runs today..Thanks"
