Algodoo

A working carburetor with only one line of script. Press the Up arrow to activate the fuel pump. Delete the fixjoint to release it from the background. The black circle with the lines can be connected to the engine to use a mechanical fuel pump, or you could leave it as it is and use its axle motor to simulate an electric pump. Feel free to use this in any of your fuel engines, and post the scene names in the comments so I can see what you made!
