Model #580767100 Craftsman power washer, gas

Question and Answers

Q:

Sears 580767100 pressure washer only runs while handle depressed.

A:

The part that is causing your trouble is the unloader kit (item 23 in the parts diagram).

When you release the trigger on the wand the pressure builds inside the pump quickly. The unloader valve releases and lets the water circulate inside the pump so the engine does not stall.

Sometimes the unloader just needs cleaning as debris or calcium can stop the valve from opening.

Q:

My power washer doesn`t start it`s almost been a year since I used it last. Have I changed all I needed?

A:

You have replaced everything you needed to tune it up. You need to determine if the problem is spark or fuel related.

Pull the wire off the spark plug and remove the plug. Is it gapped at 0.30? Connect the wire to the plug and ground out the base of the plug on a clean good connection on the engine block. Hold the plug with insulated pliers or thick gloves or a clean thick cloth. Get someone to pull the starter rope and see if the plug fires a hot blue arc to ground.

If you have this arc you have a fuel issue and probably need to clean the carburetor out or possibly replace it if you left the fuel in it. If you don't have the arc the ignition module will need to be replaced on the engine.

Q:

My craftsman power washer model # 580767100 will start but gasoline runs out of the carburetor, after it ran out of gas and put gas in it, starts and stops ?

A:

It sounds like you have a stuck float or needle valve in the carburetor. I recommend that you take the pressure washer into a Sears Repair Center and have a technician diagnose and repair this type of problem. Here is a link for the Sears Service website that has drop-off locations and labor pricing: Sears Home Services . Many areas have a flat rate pricing for repairs that is reasonable for this type of problem.
