tried to start my pressure washer w/ honda 13 hp but just cant! Drained old gas and refilled with new. Drained float bowl, cleaned black tip of jet or whatever its called, took out brass valve seat with tiny hole in center and blew out with compressed air slowly. Re installed everything and when I pull and pull...I'll get it to pop with full choke but nothing with half or no choke. At full choke itll run for a few sec then out. Its got oil, and spark or it wouldnt pop at all, Im assuming the shut off switch works too since it pops and runs for a few secs with gas poured in the air cleaner. After an hour of pulls, I noticed oil in the air cleaner housing from the pipe that comes out of the valve cover. Is this normal..? the washer has been sitting for a year and I just cant figure it out.
