    We have a the above mentioned Honda engine attached to a 2" water pump used to pump out the holding tanks of boats. For a while now when we start it will run for about a minute, start running rough and then stall out. It can be restarted again, right away, and the same thing will happen. We have installed a new filter in the tank, replaced the carburetor, removed the head to clean and inspect the valves (they look great) reassembled everything and the same problem exist. I don't know where to go from here. This problem started out slow and has gotten progressively worse to where it is today. After a few starts the spark plug is fouled black like it may be running too rich.

I'd pull the fuel hose leading to the carburetor and see how well gas flows out of this hose. if it just trickles out, the either something in the tank is obstructing it or the vent is blocked. the tank has to vent to allow air in as gas flows out to the carb. most vents are built into the gas cap by little hole(s) on it. see if the hole is blocked on the bottom side of the cap with ****. if unsure, start the pressure washer with the cap off and see if it runs for longer than 30 seconds. if it does, either clean the cap or get a new one.

also, some pressure washers need water flowing to the unit before you start it. if it senses no water, it may turn its self off to protect it. not sure how smart this washer is, but just another suggestion.

good luck

Check to see if the spark plug cap is grounding to the engine. Look for a spark where the cap is closest to the engine.

How to check oil on honda gx160

There is an oil dipstick on the side of the engine. Remove the dipstick and check the oil on the dipstick.
The oil should be about half way up the threads on this engine.
If you need to add oil you can use SAE 30 or a 10W30 Oil.

Northstar PW shuts off hot if washer is moved. Honda engine

Being petrol driven, it may have a mercury kill switch which puts a ground on the ignition circuit stopping the engine if you move it. Perhaps for safety in case you overturn the unit somehow.

Gx160 Pressure Washer runs fine for 20 seconds Then shuts off

It could be several things...oil level, make sure its sitting on level ground...if not did you use StaBil when you laid her up for the season? If not, go to Advance Auto and buy "SeaFoam" and following directions run it for as long as it will run...make sure you have water running through the pump during tests!
Good Luck

Engine keeps shutting down

Most Honda engines have an oil pressure switch that prevents engine damage due to low/no oil pressure. Make sure there is sufficient oil in the engine and that the wire is connected to the pressure switch.
