I do it everyday (cold start on LPG). I use the venturi type LPG kits. It just takes a few more seconds to crank the engine before it starts, otherwise it starts normally.

Only SGI-LPG kits need to start with gasoline but even then, I also have managed to start our car on LPG back when the gasoline fuel pump wasn't functioning. You just have to crank once and then wait for the LED light to tell you the LPG system was on "lpg".
