SOURCE: I have a Honda 3500 pressure washer. The motor

You need to start the unit and let it run for few minutes to get worm, make sure the water is fully open and the unit is fully cleaned. Push on the trigger on and off for few times not letting the unit shutdown, then start increasing the fuel mixture ¼ turn and push on the trigger again and see…this could be that the unit need service or the governor springs getting week if you got one on your unit…let me know how that work for you and please do not forget to rate my service so we can improve on it with your help. God bless

SOURCE: My pressure washer has pressure but not nearly as


Sorry, but have to ask the basics: Have you replace the nozzle to account for wear? Have you checked the inlet (garden hose) pressure and line supply to be sure it is clean and enough gpm's to supply machine? Is the supply pressure too high, so that the packings inside the pump may have been damaged? Have you removed the brass caps on the pump to clean out the little spring valves and check the o-rings?

If it acts like this with the hoses disconnected, I would guess that either you got bad gas, or if it was sitting for a while before this, that there is varnish in the carburetor and when the choke goes off it starves for fuel. I would try Seafoam or Gumout to dissolve it before taking it apart and mechanically cleaning it. If it only does it with the hoses attached, it may be an unloader valve in the unit that is sticking. Good luck.

I have a ryobi petrol blower vac which wont start checked spark nothing last time i used it it seemed down on power and slowly stopped going. What do i need to do air cleaner is good.

there are 2 wires attached to the coil around the flywheel
one wire goes to ground , the other through the start/stop switch to ground
check that that wire is not burnt through the insulation or shorting out on the motor
if that is good , it may be the coil itself
take it in to a mower shop and have it tested or replace it

Motor will not idle down

Your carburetor is the problem. Either have it serviced or get a new carburetor. You can service it yourself, you will need carburetor cleaner, very thin gauged wire, air compressor if you have one to blow out the ports etc..

Also you can check out you tube for videos on how to clean a 4 cycle carburetor

While using ryobi 100 bar pressure washer it started smoking

I take it this is an electric powered machine.

If using these pressure washers with an extension lead for the electric supply it can cause a multitude of problems. voltage drops to motor etc, which increases current and overheats the motor.

I am not familiar with this model I work with industrial pressure washers. If the type of motor is a universal motor with brushes, similar to a vacuum cleaner, then I think the motor will be toast.
if it is a squirrel cage induction motor with capacitor, then the capacitor usually fails first. this is a cylinder with either wires coming out of it or push on spade connectors for the wires.
I have meters to test these but you can usually see that the cylinder is bulging , blown the cap off or pushed out a trail of grey stuff.
hope this helps.

We have a Ryobi pressure washer. Used one time. I have no water pressure.

Could be a stock Pressure Washer Unloader Valve. You can find videos of how to remove and to clean it. It is not that difficult to do. Good luck.

Why is my petrol tank pressurised in my petrol blower?

There will always be some pressure in the tank, if the fuel in your area is poor quaility i have seen the fuel actually boil in the tank increasing the pressure and causing poor running.

Stalling pressure washer

Make sure you have a strong water supply going into it. On the two I have owned, they would struggle and the motor would "rev up" quite a bit if there was even a slight kink in the supply hose, or if the tap wasn't opened all the way.

I have a petrol pressure washer, it runs fine but as soon as i pull the trigger on the lance the motor really struggles then cuts out after a little while

Your unloader on your pump is working but when you ask for the engine to work it struggles I would check the air cleaner the passage in the carburetor could be slightly plugged starving the engine for fuel check and make sure the choke is fully opened your problem is for some reason the engine isn't providing the horsepower needed maybe try backing off the pressure regulator.

Gday folks have a 163CC 2500PSI RYOBI® RPW2400 Petrol High Pressure Cleaner that cuts out after about 5 to 10 seconds Nothing obvious to me. any suggestions would be grateful Thanks Marc

Check fuel delivery to the carburetor--if just drips, check the fuel filter for plugging. Make sure you have fresh fuel in the tank. Hope this helps!

Ryobi RBL30MVA petrol blower problem

if this is a brand new I would ask is the gas oil mixture fresh and of the proper ratio. most use 40-1
if this is not brand new look and see if the muffler could be clogged up. a common problem is the spark arrestor screen gets clogged up with carbon deposits.
