Trying to help a friend with a Honda Pressure Washer and from the looks of it hardly used. When I got it there had been a significant mouse infestation so I pulled flywheel and cleaned out all mouse nest/debris. - replaced fuel - new spark plug and ignition coil (which had been chewed on). Spark test shows spark. - I was able to get it started briefly with starter fluid, but wouldn’t keep running. Figured it was carb problem, but I cleaned it out multiple times and still nothing. - Checked rocker arms / looked good and gaps were fine on combustion and exhaust sides. Completely stumped at this point. Any advice? Quote #1 1 Reply Related Threads

Does the machine have a fuel pump? Did you remove / clean the little jet located under the idle stop screw? There's a small, black "spacer" that'll come loose when the screw is removed. Under that is a black plastic and brass jet with an extremely small jet. You can use a wire, cut off from a wire brush (held with a vise grip) to get it clean(it's that small). Quote #2
