The pressure washer sat for about 2 years. I was waiting on a new pump from the manufacture. I just put it on. When i started it up it wouldnt idle correctly. The gas tank was empty the whole time so the gas in is fresh with a light amount of Lucas fuel treatment. I took the bell housing off between the carburator and air filter. There is no varnish. I also ran a full load of fresh fuel thru. If i leave the choke on and spray it works fine but as soon as i realease the choke it shuts down. Also if i push the choke in halfway without spraying it revs up and bogs down and it goes back and forth

How to Identify and Fix Common Gardening Problems ?

If the engine starts, but does not run smoothly, it means that the spark plug and ignition system are in order and you need to look elsewhere for the source of the problem. The usual culprit is air intake or fuel system related.
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
The mower surges when the carburetor sucks air through an unsealed gap in the air intake manifold instead of through the air filter. Dirty carburetor. Clogged fuel jets inside the carburetor commonly cause the lawn mower engine to surge. Clogged jets can`t provide the right mix of air and fuel to the engine.
Clogged or Dirty Air Filters

It is one of the most common problems that cause lawnmowers to sputter. The mowers take the air from the surrounding through air filters and mix it with fuel inside the engine. So, if the air filter is clogged or dirty, it will affect the flow of air into the carburetor.

Power surges occur when the flow of electricity is interrupted, then started again, or when something sends electricity flowing back into the system. Surges can range from five or ten volts when you turn on your hair dryer to thousands of volts if lightning strikes a transformer.
This is caused by a rich/lean cycle at idle. As the motor leans out the RPM`s increase and richen up the motor, when the motor richens the RPM`s decrease and the motor leans out again. This continual cycle is known as “blower surge”.
Low fuel pressure can cause a backfire when there`s too much air and not enough fuel in the combustion chamber. This can be rectified on lawn mowers with speed settings by simply increasing the speed and thus increasing the fuel supply. Another possible cause is a failing fuel pump or even an old fuel filter.

The engine idles way too fast and will not correct with the sow speed adjustment
ANSWER : Make sure that you are adjusting the idle speed screw, not the idle jet screw (L). If you are adjusting the proper screw, then it is possible that the throttle trigger assembly in the handle has a load of sawdust/dirt that blocks proper return to idle. Take the handle apart carefully, and make notes on how the parts go back together. Check at the carburetor throttle assembly to make sure the throttle arm returns fully to the idle speed screw when the trigger is pulled and released slowly. Check the throttle spring as well to make sure it is undamaged. Hope this helps!
