Gerry,
That makes sense, making sure there is fuel before mixing in ether. My Detroit has a hydraulic govenor, which requires a manual overide of the rack before it starts injecting fuel. I usually crank until it starts pumping white smoke, then give it a little shot of ether. Initially it barely starts popping, then gradually starts firing well as it warms. If I had electricity nearby, I'd try a block heater, but that isn't available. It seems like the glow plug option would be a useful addition for listeroids in really cold areas, but my climate just isn't that cold usually. Likely I'll rely on a tad of ether if needed. Incidentially, George B shipped a listeroid for me yesterday, should get it next week, and have a bit more to discuss.
