I think it is getting too cold for the electrons to flow and your need to create a siphon so that there is better flow. Get a large wire, maybe 0 gauge and hang it down further.
The old cars like Gump just have the yank on it to glow knob. Requires some subjective calculations to determine the effective amount of pre-glow needed. At times it will go through three pre- glow cycles before feeling that enough electrons have gathered to create critical mass. Combustion follows. clay On 7 Dec 2007, at 06:50, Wonko the Sane wrote: > About this time of year, my glow plug system gets a mind of its > own.
