There is a good chance the motor or carb aren't original. I thought I tried all of the screws at the local hardware store but maybe I didn't. I think you understood me on where the 4 screws are at. The screws go through the piece that the air cleaner also attach to. I will try and track some 12-24 screws down at the local hardware store. Is a 12 series screw the same as a 3/16?
Thanks, Dave
