i have a 1972 evinrude 40hp model number 40253E the starter stopped working so i took it off and removed the end with the gear. when i looked down in it at the brushes i noticed the terminal wire was not connected. this is where im at. i think i can take the four screws out of the sides of the body of the starter and pull the bottom off and repair the wire, but the 4 straight head screws will not budge. does anyone know of a way to get these out without detroying the screws? thanks Dennis
