Technically yes. Propane systems do not have a choke but most of them have a "primer" system to make up for leak down pressure losses and low cranking vacumn on cold starts.
Most systems will lose the fuel charge between the outlet of the vaporiser and the inlet of the mixer overnight so without a primer you would have a long crank when its cold, and on bigger engines in hd trucks the cranking vacumn is low so that somtimes they do not create enough to open the vaporiser so a primer gives you a "shot" of fuel to overcome this.
Hope this helps
