Insanemoondoggie's fix is viable and I do the same thing but keep in mind what keeps a normal needle tightly in place. It's not the threads and it's only partially done by that little metal clip. That thing is to give to a physical feel (clicks) when you adjust the needle. There is a rubber O-ring on the needle. If it gets worn you can have engine running difficulty in the near future as air gets sucked in of fuel gets blown out of it.
There are two "lock" clips on the needle. The clips work well until you get about 2 turns out, then the detents on the clips start to become un-effective, the detents that set in the grooves do not run the entire length of the clip. Poor design in my opinion.
