RE: Need Glow plug help
Take a close look at the element in your plug. Is it shiny and silver, or sort of frosty-white looking? Maybe a little rough and bumpy rather than smooth? Sometimes plugs get coated with something (I've heard silicone, which becomes silica, or glass) that keeps the platinum in the element from reacting with the methanol in the fuel. That catalytic reaction helps keep the plug glowing when you remove the batterey. If it doesn't take place, running becomes iffy without the heater.
