2300 psi power washer stopped,

Pressure washers work under very dirty conditions, no wonder they encounter engine problems. Here are a few pointers from a former pressure pump tech. The unloader is a source of engine overloading however this can easily be checked with a pressure guage attached to the gun with a tee fitting having the guage and the normal tip used for the unit. The pressure should never rise over rated pressure. The pressure should drop considrably when trigger is released. The life of the pump and engine can be increased by setting max pressure to 75% of rating. Most engine problems are from following conditions:
Leaking or misadjusted valves; clogged muffer /spark arrester; weak spark coil that is about to fail completely; kill switch/oil sensor wiring and or sensor mal function; gas cap not venting properly causing vacuum in tank and wet or dirty air filter.
All these problems easy to check, fastest repair is to disconnect oil sensor wire to check oil safety system. Then temp replace coil with known good coil. Loosen muffer bolts to check for clogged muffler. Temp run engine without gas cap to check for vacuum. Finally if everything fails, run the engine with carb cleaner spraying directly into the intake. If the engine continues to run with carb cleaner then the problem is fuel delivey and faulty carb. enjoy

Hi

When lever is turned to stop position look under the levers" support and see if there is established a conection with the wire from the coil wich kills the running engine.Also check the conductivity of that wire.

You say you cleaned the carb. If you did that by spraying cleaner in through the choke, that's good, but it doesn't get to the root of the problem. The problem is getting the gas into the carb. Try this. drain the gas. Put a small amount of carb cleaner and gas in the tank (about 1:1) Start it up, but don't run it dry. Let it sit for an hour. Then start it up and run the tank dry. Then try just a little gas to see if that fixed it. If not, repeat. Good luck Al K

There are a couple of things that can cause this problem. The first thing to check is if you are loosing spark. Dying after it gets hot sounds like to stater is failing in the engine. If you loose spark this is more than likely the issue. If you are not loosing spark you need to check the fuel system. Dying after 20 seconds it could also be a plugged main jet in the carb. Another common issue on Honda engines is a faulty vent on the gas caps for engines sold from around 2008 - late 2010. If your gas cap is only about 3/8" thick this is very likely to be your issue. Try running the engine without the gas cap on to see if it still dies. If not that is your problem.
