RE: Glow Plug Idle Bar
Never mind, did a search after asking the question and found lots of answers. Smart huh?
Copied from another post somewhere. Please let me know if this is incorrect information.
Thanks.

No but. Idle bar plugs came out when engines had a baffle across the piston which directed air from the intake port up into the cylinder. Fuel would stick to the baffle and fling off as small droplets. The idle bar stops the droplets from hitting the element. They do nothing for inverted engines. Since they are largely used on these older engines the heat of the plug is made to suit them, mostly slightly colder than say an OS #8. Unless you are running slightly higher nitro than most then a modern plug would most likely work better.
