I would think the use of a 1.5 volt glowplug driven with 2.4 volts should give a lot of help to the catalitic action of the plug. The thing I am wondering about....will the plug burn out sooner than it should? I would imagine there are a lot of glow plugs to try also. How about a GlowBee....I think that is the one with a flat coil??? Not sure. Keep up this very intesting project. Thanks Capt,n
