Question about Honda Karcher G2400HH-R Pressure Washer

1 Answer

Not enough pressure

Got a 2400 psi karcher pressure washer and it is surging. Not a steady spray. We put in a new spark plug. drained gas and carburator. Used new treated gas. Still surges? I have a pressure washer that surges whenever I press on the wand. The pressure is on for about 2-3 seconds and then it dies down like a water hose pressure for the same amount of time. It keeps doing this the whole time I press on the wand

SOURCE: not enough pressure

Speed regulation on small engines is notriously fussy.
Check the linkage to the carburetor and look for a small, light spring.
If there are several holes for one end of it, you may have to try more than one to find the spring tension that lets the engine run steadier than it now does.
If not, then either replacing it or changing the length by shortening or lengthening it will probably be needed.
