Open the throttle a bit to get the higher idle. Mark a line on the two pieces of tape (so you can hold the throttle in the same place else it's hard to set the air screw). Clamping it is even better.
For the software, see Adobe Illustrator. An illustrator is an artist who specializes in enhancing writing or elucidating concepts by providing a visual representation that corresponds to the content of the associated text or idea.
Illustrators solve visual problems and tell stories in formats that range from infographics to comic books. You can make 3D visualizations, book covers, posters, cards, graphic novels, collectibles, and more, and are responsible for managing and maintaining their own business.
