I have a Troy Bilt gas power washer model #020413, 2500 max PSI, 2.3 max GPM machine. The engine starts just fine, when I try to squeeze the trigger for the power washer wand, the engine just shuts down (water connected and turned on prior to engine start). Then the start cord is really hard to pull. Turn off water, squeeze trigger, release pressure, turn water back on, squeeze trigger, water comes out, start engine, engine runs fine, squeeze trigger, engine shuts off.

Is it the unloader valve, is it the pump, is it something else, is the machine just shot and I need to buy a new one? Thanks for any help.

This definitely sounds like the unloader valve.
Here is a video on how to clean it.



Also, make sure that your wand and gun are working. When the unit is turned off and the water hose is turned on, does depressing the trigger cause a flow of water out of the nozzle?

To avoid spending a lot of money on repairs, it is better to buy a new pressure washer. I was looking for a good one myself, but I couldn't find one, because there is a huge selection on the market and it's hard to choose. I ended up buying a ROOJER(2.6 gpm flow rate, max PSI 3500 psi), trimthatweed.com/best-3000-psi-pressure-washer/ helped me with my choice. Maybe you, too, will help with the choice of new equipment. They talk about the best 5 pressure washers out there. All the specs are detailed, I think you'll find something for yourself.

You should go for a new one if you have difficulty finding the same old things. I tried this  golf-tipsandfacts.com/  and proved very helpful.
