It has something to do with how you start the engine, the tank on the back is a compressed air tank, there is a separate small HIT-NN-MISS gas engine with a antique air compressor that pumps up the tank, you pull a lever and move the cam followers off the primary run lobes (that actuates the valves and allows fuel to flow). SOme how there is a position where it opens valves and lets the engine spin free of compression... Pull the lever and then the intake and fuel metering valve starts to work...

It works pretty much like your new hemi.... Minus the blower....
