On the high speed needle, just pulling the pin is fine.
On the low speed needle, you can yank the pin out with a pair of needle nose pliers.

Sorry but this is not enough...
The problem is that the blue collar itself is affixed via a grub screw to the needle.
As you turn the needle the limiter collar is STILL doing it's job, because the needle cannot be turned in further than the collar permits.
The grub screw on the blue collar and the collar either removed or pulled up to permit further unrestricted travel.
This is not obvious, and drove me nuts the first time I yanked the limiter pins on an Evolution engine.
