On the carbs, you’ll notice the cable support screws (240357) and choke housing screws (841360) often have “dashes”
stamped into the screw face. This is to designate that the screw is not actually a Phillips, but rather a Pozi Drive. See
included pictures. Pozi Drive #2 screw drivers are available from professional tool suppliers. Most techs are unaware of
the difference and use a Phillips screw driver, which strips the head on these screws.

On the carb sockets, you’ll notice the screw used for tightening the socket to the carburetor has a “dot” stamped into
the head. This is to designate that the screw is not Phillips, but rather JIS (Japanese Industrial Standard). See included
pics. If the techs switch to a JIS screw driver or driver bit for the carb sockets, they’ll notice a much better fit. #2 JIS
screw drivers are available from professional tool suppliers. Often people strip the carb socket screw head, because
they use a Phillips screw driver. The screws are not available as a spare part, forcing the technician to replace the whole
socket assy.
