The type of oil recommended for that engine is SAE 10W-30 and the capacity is 0.61 quarts. This and more can be referenced at the website at the end of this solution. I was able to find the owners manual of your particular engine.

The only way to get down to the bottom of this is to get yourself the necessary fittings and high pressure gauge so you can read what the line pressure is while the trigger is released and applied.
You have to get down to the source, find out what it is.
Could be a bad pump, bypass valve, debris inside trigger, or spray tip is worn out or is too big for the unit it has been attached too (not enough GPM).

Your choke controls the mixture of fuel and air. An engine will run rich if it has a restriction to air flow. Try removing the air cleaner, if after this you can turn off the chock you have a dirty air cleaner.

If you are using a water tank for water supply, remove the water supply line from the pressure washer and connect a water hose from a faucet. Turn the water on, then crank the engine. Pull the trigger of the spray gun until water comes out. When then water starts to spray properly the release the trigger, shut engine down with pressure on the line then reconnect the water supply from the tank to the pressure washer. If this fixes the problem then the problem was "air-locked"! Happens alot with new pressure washers that have never been run. If you need any other help, please email me @ [email protected]

No, but it sounds if the carb needs to be cleaned! Fresh fuel helps too. Check the spark plug and check the breather filter. Also you can crank the engine with the breather filter off and try to move the choke to run then. If it runs with the filter off then there is your problem! 1 question, has anyone try to work on it or adjust the carb in any way?

Sounds like the unloader (regulator). Try removing the nozzle, the pull the trigger with the engine running. If motor is still running then it could be the Unloader malfunctioning. If you require a new one try a bypass system for the unloader. The bypass will help save the life of the unloader.

Turbo heads are pressure rated for different pressure washers, your turbo head is most likely rated bellow the maximum pressure of your washer which in turn causes a pressure build up in the hose and it's eventual failure.

carburetor needs cleaning/rebuilding/replacing

Honda Pressure... | Answered on Aug 24, 2014

sounds like your pump or motor seized from overheating which makes parts swell / grow in size/expand so they stop working ,,,letting cold water flow through the pump would have cooled the parts and help shrink the parts again .. Overheating can do permanent damage to your machine.. I think it needs to be dismantled and inspected for damage by someone who knows what to look for. not sure if the problem is in the pump or the motor, hope that helped.....pete
