i know now how to do it for a briggs § stratton quantum 55 : maybe it helps: remove plastic topcover ( 2 screws) , remove fuel reservoir ( 3 bolts) , remove assembly ( 2 bolts located above sparkplug and 2 bolts located opposite the sparkplug, that is somewhat 10 centimeter below the topsurface of assembly). Remove assembly inclusive oilfill pipe .Turn over the assy to see center screw . removing centerscrew allows to dismantle other parts
