Working on a Kawasaki ninja motorcycle I needed to adjust the carb enrichment screw. If you are familiar with them the screw is underneath the carb. So you cant see how many turns you have made. This is a simple pointer to put on a flat head driver bit so you have some reference to what you have done. This item is not very complex but what i am trying to show is just how having a printer can make things to do everyday jobs much easier.
