Does anybody have a picture of the underside of a garelli head stock? My head has been milled down and there is nothing but a flat part and of course the sphere where the plug is. When I look at the diagram on mopedjunkyard it looks as if there is supposed to be a lip around the out side? After reading the two-stroke tuners handbook I am reading about the squish area and in the pic it seems this should be angled with the dome of the piston. Well mine seems to be just as flat as everything else is this ok?
