Accidentally used kerosene in pressure washer. Have drained the kerosene out but it still won't start! What else do I need to do?

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

Sounds like you need to clean the carbs out, as they are probably gummed/varnished badly after sitting for 2 years.

Water promotes rust. Go to the paint store and get some varnish remover. Put a gallon in the tank and follow manufacturers directions.Don't get any remover on the outside of the tank!

Considering the age of the bike I would get a liquid tank liner.

Google “ kreem fuel tank liner “ or go to www.http://www.4secondsflat.com/Fuel_Tank_Sealer.html

Hello cikanek:

Try this:

From your posting, I assume you have removed the splash cap and the nylon bypass valve cover. Connect the water supply to the pump and connect the high pressure hose and wand to the pump outlet. Wad up a small towel and place it over the bypass valve opening to catch the valve insert when it pops out. With the engine throttle closed, pull the starter cord several times to see it the valve insert will pop out. If it doesn't come out after two or three pulls, set the throttle to low and start the engine. I have performed this procedure a number of times and the valve insert always pops out. There is no real danger of the valve parts getting seriously airborn since the actual pump output volume is very low (2.5 Gal/min).

Good luck,
Ed

turn the fuel off when not in use,it is going through the carb.to the oil.
