It is not a big difference, but it IS noticable.
What if there is a small plastic disk under the fuel nipple of the solenoid casing with the hole in it?
Also in setups where the solenoid is external from the carb just plugging the hole where the needle holder used to be might work too.
Then just use the original fuel nipple and possbly install the restriction disk under that.
Not having a needle stick out will make the carb much less vulnerable to crash damage like the os la series of engines.
On the other hand the simplicety of just mounting it on the needle holder also has advantages in other situations
