1910 Jopson Motor Carburetor

One of the most unique features of the 1910 Jopson Motor is the wick carburetor system in the fuel tank. A small plate on the tank holds a series of wicks that are immersed in the fuel and evaporate fuel vapor into the passing air stream, which is then pulled into the combustion chamber.

Art was able to take his engine apart and he documented the wick system (still intact after 100 years!) in photographs and drawings.

drawn on yellowing grid paper, this hand drawing shows the layout and every measurement of the fuel tank.

A close look shows that the six wicks are actually three lengths of rope that have been threaded in half through the holder.
