I don't have enough money for a reamer right now sadly, but like I said PB Blaster and a pipe cleaner did a good enough job to clean off the threads.

I have the glow plug installed comfortably in and my indicator light is happily orange now
There is more to the story. Carbon build up shortens the life of the Glow Plugs. It allows heat to be trasfered into the Cylinder Head insted of heating the Air in the Precombustion Chamber.

I hooked up a Single Glow Plug (the Glow Plug was not in the Engine) to an Amp Meter and found that it maxed out my 60 amp Ampmeter and aver a Second or so as it got hot it settled down to about a steady 16 amps.

What I concluded from this is that if something conducts the heat a way from the Glow Plug it will continue to pull the higher amps. I think that is what shorten the life of the Glow Plugs.

In the Pic between the Red Bars is the area the Carbon builds up in. You can see how Carbon build up that actually contacts both the Glow Plug Tip and the Cylinder Head can conduct heat into the Cylinder Head.
