Ya' see, that's where I get lost...glow plugs. Are there different numbers for the plugs between manufactures but have the same heat range?
Example: Tower plug "A" is a cold plug as opposed to O.S. plug "A" would be a medium plug?
What I have in there now is an O.S. 8 and I'm running [link=http://www.morganfuel.com/cp_blends.htm]Cool Power 15% - MV [/link]
Someone said in an earlier post that a long plug is good for these engines. I get the "long" part, as in more length, but they didn't state what heat.
Don't blame yourself for being confused, Crispyspa. It seems as though the glow plug manufacturers have done their absolute best to confuse we
modelers as much as possible - and they have succeeded. Now that I think of it, this subject would make a great magazine article for some
knowledgeable modeler to write. Hint - hint!
As you may have guessed, there is no universal rating system for glow plugs, so making judgements based upon number/letter combinations is impossible. Even within the same brand of glow plug, in some cases.
