Small Engines (Lawn Mowers, etc.): timming a pressure washer

Question
HELLO MR. JONES HOW ARE YOU? MY FATHER IN LAW HAS A HONDA PRESSURE WASHER , AND WE CANNOT GET IT STARTED. HE TOOK THE VALVE COVER OFF AND THE VALVES ARE WORKING OK. THE PROBLEM IS HE TOOK THE PLASTIC GEAR OFF TO CHECK THE BELT AND NOW I BELIEVE IT IS OUT OF TIME. DOES THE HIGH POINT OF THE CAM MAKE A DIFFERANCE? THE ENGINE IS A HONDA GCV190LAN5AP   EF;BHNXS.1871AA  GJAAA 2402941 I HOPE THIS INFORMATION HELPS THATS ALL I COULD FIND ON THIS MOTOR. AGAIN I APPRECIATE ANY TIPS ON THIS ENGINE, THANKS.
