I would strongly recommend that you take it to a local small-engine repair shop. When an engine is stored for that length of time, the gasoline that is in the fuel tank, line, filter and, most importantly, carburetor breaks down and leaves a gummy residue behind that will clog the system.

The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.
Give Your Pressure Washer a Break

No matter how powerful your pressure washer might be, it`s never a good idea to leave your machine running for too long because doing so will increase the risk that it will overheat. Instead, most professionals suggest using a pressure washer in intervals of three to five minutes.

One of the most common reasons a pressure washer won`t stay running is because the spark plug is dirty or damaged. To clean the spark plug, you will need to remove it from the engine and use a wire brush to remove any build-up on the electrode.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
The simple answer is yes, pressure washers can overheat. This is not unique to pressure washing machines – anything with a motor or power source can overheat in the right (or perhaps, wrong) circumstances.
Each time the power cord is plugged in to an outlet, the Reset button on the GFCI module must be pressed down to connect to electricity. Check to see if the Reset button has been pressed. Next, confirm the small plastic window below the Reset button shows RED in the window.
It Can Harm The Unit

A pressure washer requires water to cool and lubricate the pump, which is the part responsible for pushing water from the supply hose to the nozzle. Without water to cool and lubricate it, the pump will work harder than it should, causing it to wear down quickly.

Fuel that has been stored for over thirty days can go bad and damage key components on your pressure washer. If possible, drain the remaining fuel into an approved container, like a gas can.. If that`s not possible, add fuel stabilizer to prevent the gas from breaking down and gumming up engine components.
Pressure washers operate under pressure, and that pressure needs to be released by pulling the trigger. If you let the machine run for two minutes or longer without spraying water, then you could damage the pump.
Overtime the intense water pressure can cause the nozzle to become worn out, plugged or misshapen. This causes more water to flow through the nozzle, diminishing the pressure.
If the pump is leaking, the cause may be minor and easy to repair. Check the seals, packings, and O-rings for wear. These can easily be replaced, saving you the cost of a new pump. However, major leaks such as the ones caused by cracked or damaged plungers, can lead to pump failures.
One of the most important features to look for on a large semi-pro gas pressure washer is variable or adjustable pressure controls. This way you can tailor the strength of PSI depending on your cleaning task. Variable pressure is especially important on power washers as powerful as these units.
Should the light flash on my Window Vac when charging? The light on your window vacuum will slowly flash continually until the battery is fully charged. It takes 90 minutes to fully charge from empty. Once the battery is fully charged, the light will become solid.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
Surging occurs when the pressure is fine and then weakens. It is caused when the flow rate for the pump cannot be supported by the water supply. Problems can mount from there so it is important that it is dealt with as soon as possible.
