Do you have good compression,also check for a sheared flywheel key.

Will a shot of gas in the spark plug hole allow it to start up for a moment? Have you checked compression?

its funny i was just thinking that this morning,,i will try that.also put gas in spark plug hole,removed valves and re seated,then i started to throw the pressure washer down the sidewalk and lite it on fire then beat it with a sleghammer,then i put it up ,so i woke up and thought it could be the flywill key?so i am gonna try that,then if that is ok i will try compression test.i am really think it has got to be timing because there is suction when you put your finger over spark plug hole..............what else could it be?hhhhhhhhhhhhhheeeeeeeeeeeeeeellllllllllllllllllllllllllpppppppppppppppppppp,thanks for your quick response...i will be checking for any help i can get.will let you know how it goes
