This is for the Briggs and Stratton, basic operations should be the same for the Honda engine.

sounds like a briggs engine, DONT remove the rivits, go down a little further and remove the 4 3/8 bolts that hold the blower housing on.Turn it upside down, prewinf the pulley in the direction that it turns when the rope is being pulled. When it stops turning because the spring is tight, let it unwind one turn and line up the hole in the pulley with the hole in the metal part where the rope comes in and slip the rope in, tie a not and melt the freyed end. Let the starter pull the rope in by itself.

What fluid and how much is required in the Troy-Bilt 2550 power washer pump?
