Honda GCV160 5.5 on a pressure washer runs only intermittently

If pressure washer got frozen over the winter, the pump is bad. replace! Use winter pump protector during winter storage!

Rebuild the carburetor. Just replace the old gaskets, diaphragms, needle and seat. You can get a rebuild kit from your local lawm mower repair shop. also, don't run last years gas and if you keep gas in the tank over the winter buy a winterizer and pour it in the tank when starts to get cold. Hope this helps!

Likely the gas it bad you can,t leave fuel in tank over winter with out gas stablizer You have to drian the tank and remove the float bowl from carb and lite that drain then put it back together and it will run with new gas may not run good for first 5 or 10 munites but will smooth out

Then, let it sit for 48 hours and don't run it at all. This is how I fixed my no pressure problem [email protected] owner of Honda 5.5 with Comet pressure washer pump</span>

pour a large amount of carburator cleaner into the gas tank
run the engine for five minutes then shut it off and let it sit for a couple of days.
then start it and see if it runs any better
the longer you let it sit with the carb cleaner in it, the better it should run

Check the inlet strainer where the water supply hose is attached,this is located just inside the coupling where you hook up the water hose.

Any possibility the unit froze this past winter? They do have to be winterized.

sounds like you need a seal and bladder rebuild < if you liver in a cold environmet for winters please dont forget to winterize your washres every year before winter

not quite sure where to get the parts, but if the pressure starts out ok and decreases as it runs, it is generally that the piston rings/seals are worn out, this can happen just from sitting up over the winter.

You can google Honda Pressure Washer Parts to find a supplier for the seals/rings

well for starters if you let it sit all winter you the pump probably froz up and you might be able to get it un jamed by pouring in oil (any kind) in the hose inlet and let sit one night the try starting
