I put 2 cycle gas with oil in my pressure washer. I drained it and put in regular gas but it still wont start. Any suggestions?
Remove and empty the carburetor bowl, remove the spark plug, pull the start rope seweral times to get rid of the faul fuel from the cylinder, fitt new, or clean and fitt the old spark plug back, drain the fuel tank and fill up with clean fresh fuel.
Did you pull the spark plug out and clean it ? if you did , did you also put the starter cord and turn the motor over without the plug installed to get rid of the 2-cycle oil out of the cylinder ? if not do so.

You can try spraying some carburetor cleaner into the carb. If it starts for a minute, your carburetor need cleaning. When you added new gas did you remove the old gas first? Is the air filter clean?

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

Buy a new plug, drain out all of the old gas and put in new gas, and take a look at the air cleaner. If the air cleaner is dirty replace it. There you now have a good spark, good fuel and good air. The engine should start. If it doesn't get some carberator cleaner spray and some starting fluid spray.

what about the linkage between the governer and the carb. Is that working and not binding?
