SOURCE: pressure washer stalls

Pressure washers work under very dirty conditions, no wonder they encounter engine problems. Here are a few pointers from a former pressure pump tech. The unloader is a source of engine overloading however this can easily be checked with a pressure guage attached to the gun with a tee fitting having the guage and the normal tip used for the unit. The pressure should never rise over rated pressure. The pressure should drop considrably when trigger is released. The life of the pump and engine can be increased by setting max pressure to 75% of rating. Most engine problems are from following conditions:
Leaking or misadjusted valves; clogged muffer /spark arrester; weak spark coil that is about to fail completely; kill switch/oil sensor wiring and or sensor mal function; gas cap not venting properly causing vacuum in tank and wet or dirty air filter.
All these problems easy to check, fastest repair is to disconnect oil sensor wire to check oil safety system. Then temp replace coil with known good coil. Loosen muffer bolts to check for clogged muffler. Temp run engine without gas cap to check for vacuum. Finally if everything fails, run the engine with carb cleaner spraying directly into the intake. If the engine continues to run with carb cleaner then the problem is fuel delivey and faulty carb. enjoy

SOURCE: changing engine oil on a gx390 engine for pressure washer excel

On the very bottom of the motor is a square plug to drain the oil. The machine must be elevated to allow the oil to flow into a drain pan. If you don't see a square plug then look for a small 1/4 inch tube coming from the bottom of the crankcase with a hex cap on the end of it. If you cannot find either of these, then you must turn the pressure washer on its side and drain it through the same plug you fill from.

SOURCE: I want to remove the 4gpm pump on my pressure washer.

HI, It sounds like it is just stuck on the keyway as these can be very tight. You need to force the pump of evenly on either side and should come of if patient.

I'm sorry if I'm not quite understanding the question.

Are you saying the rope MAY be too short and so the amount of pull available is also shortened?

What kind of pump oil for simpson gcv190


I need to know the model of the pump you have. You are giving us the model of the engine which is a Honda GCV190. Can you tell me the model on the pump itself. It is more than likely an AR pump but I need to know . It is more than likely going to take 30 weight non detergent but some pumps take specific oil. You can also call Barens at Pressure washer parts catalog quick links Pressure Washers High Pressure... They can hook you up with the correct oil for your pump. Good luckOADXAV

Motorturns over hard with pullstarter on my gx340 pressurewasher


You have a nice setup, lots of power. The honda gx340 has a compression release built into the engine so it should be relatively easy to start. With the pressure pump under load however, it will be very hard to pull the rope. With water connected hold spray gun open so water is running out tip and pull rope to start (for easy start, remove tip from gun) . If it still feels very hard to pull rope while holding gun open, most likely problem with lubrication in pump or engine valves are not adjusted correctly preventing compression release. If you suspect problem, go to store where you purchased the unit or any store that sells gx340 and pull the rope to get a feel of what force is required to start engine and compare to yours. Good luck.

Honda GX340 11 Hp ..Runs fine until it gets hot , Cuts off and


FIRST...check the engine oil level. Some Honda engines have an oil sensor that shuts off the spark if the oil is low. This would also explain it shutting down when it get hot. Check the manual to see how to tell if the oil level is correct. Also, the oil should be brown and transparent, not black. It may need changing. Post again if this doesn't help :-)
