RE: Open discussion about the glow engine's carb
Yes,
The limitation with that is that the tape tends to sherd with the back and forth action needed to tune an engine. These shreds can cause havoc in tuning and trouble shooting as they block or partially block the metering ports inside the carb. The best thing I have found is some dry film lube that is baked to a chemically resistant coating then allow the needle holder's threads to cut this rather soft coating making a rather nice knife edge seal. I have also used electroless nickel plating in an attempt to build up the thread. While nickel is soft it was still too hard to allow the thread holder to cut a seal into.
All the best
