Gas pressure washer will not start

Karcher Model G2650 OH with Honda 6.0 HP, GC 190 Engine. Engine won't start. New gas, has spark. Seems to flood instantly. Much gas in cylinder. Spark plug wet. Choke pulled out, power on. Oil OK. released pressure in line. Where can I down load a Honda Engine manual! Thank you !

Every 5.5 HP pressure washer runs between 2,200 and 2,500 PSI with most set by the manufacturer at 2,400 PSI with 3,600 RPM of engine speed.

Due to the power required to produce more than 2,500 PSI a 5.5 HP engine would lose engine speed as it can not produce enough power for the higher PSI output. It is a matter of hydraulics vs input power.

Any gas pressure washer will produce lower pressure with lower engine RPM. Looking at S2350 as your model number yours may be set to 2,350 PSI by Simoniz.

Thanks for using FixYa.

Hello:
Have you tried changing the gas, Especially, if it has been in the machine of a while. Also some Honda engines will not start if the oil is low. Also try removing the high pressure hose before you start it? Do not run it very long without water flowing through the pump, though.

Clean the carb. Change the plug. Get some start fluid but use sparingly. Run the water (pull the washer trigger) while you are trying to start the engine.

replace the fuel carburetor filter and, or, your fuel tank filter

This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.

Honda engines are know to be very well and durable.

well for starters if you let it sit all winter you the pump probably froz up and you might be able to get it un jamed by pouring in oil (any kind) in the hose inlet and let sit one night the try starting

Remove and clean the carburator. Sound line a stuck needle on the float. 

call up karcher and tell them your problem
