With a restrictor you will have less air entering the carb, so therefore, you will have more fuel than you need, and so you should lean the carb a little. But don't do any tuning until it has seen several minutes around the track of course.

I used carb restrictors on my Picco XP and I didn't have to change the needle settings. The restrictor is slowing down airflow.

It's a plastic insert, for the carb. There are actually a few inlet hole sizes to choose from.

The restrictor as it's name suggest, it restricts the air flow into the engine.. making it more fuel efficient but loses some rpms though.

Those engines with a big bore carb, like the NS12, comes with this kind of air inlet restrictor.
