On my super skybolt and my P-47 topflite, I opted for remote or on-board glow. The skybolt was converted to direct due to the onboard glow was making tuning the low end a nusance. But one or two times I did flood it, all I do is rotate the prop until the carb or exhaust port is open and tilt the plane that way to get the fuel to flow out. On a fully enclosed engine for scale looks, I try not to punch excess holes if I can get away from it. On the P-47, the fuel and glow have a hatch that you can access the glow and fueler. The skybolt and the jug bolth have the main needles out in the open for tuning, but that is all. I even try to hide power switches, it also serves to protect them from castor oil residue too. If you have really low clearence inside the cowl, but want remote glow without anything sticking through the cowl, you can use a 3/32 wheel collar drilled out to .101" and replace the setscrew with a short 4-40 thread cap heasd bolt, grind the chrome plating away on the side and solder your wire to the side of the collar and slip a piece of plastic between the collar and the plug for a insulator. Snug it, but don't go nuts, you can snap the tip off the plug with the torque if not careful, now your done and it's the same height as the top of the plug tip and secure.
