Some of you may know this already, I did some experimenting this AM., I removed the gasoline carb from my FG 11 and installed a 56 sized glow carb just to see if it could be done. It can and it's easy, you can use the same intake pipe but need to change the back plate. The gas carb is mounted with 2.5 x 25 x .45 screws, the glow carb is mounted using 3 x 20 x .5 screws. The reason for this madness is that the 56 cylinder I was excited about was partly mis-labeled. It is actually for a 200 radial and the FG 11 having a 27 mm bore. So, I'm going to build a .66 glow engine.
