The engine catches fire when the throttle is applying too fast, until the engine reaches 6000 rpm. After that you can move the throttle as you wish. So like gaunt1 says, set the throttle to 0, select the first engine, start, deselect, select the second engine, start, select both (all) engines. When the RPM indicators settles just above the zero, gently apply the throttle.
