After you have fueled the tanks....and before you connect the glow,
spin both engines to make sure they are not flooded, or hydro-locked.

Now, put you finger over the exhaust outlet, and spin the motors for
three seconds each. This will pressurize the tanks, force fuel to the carbs,
and the motors will suck in fuel....and be primed.

Now hook up the glow....and spin the motor....it will start instantly....
