Unfortunately that is not quite so.

The blue collar holds the needle firmly and it prevents it from screwing "IN".

The grub screw on it must be loosened and the collar must be pulled ( or removed ) up a bit and retightened too.

I'd recommend that you DO NOT pull off the pin.

Instead loosen the grub screw and temporarily remove the collar altogether.

Now get the engine tuned up and running well.

Go through the standard tuning, pinch tests, nose-up, nose down, transitions, etc.

Once done put the collar back on, and being careful NOT to move the needle itself, set the pin about half way between the stops, then tighten it down. Just be sure that the collar does not fully "seat" against the black metal retrainer/restrictor..

Now the limiter will properly do it's job. You can move the needle in either direction about 1/4 turn for fine tuning , w/o running the risk of going too far.

As the weather changes you'll be glad you did this.
