Default Picco bost 21 5t-r

I Just picked up a brand new Picco Boost 21 5T-R Team spec engine. It came with two venturi inserts for the carb a 7mm and a 6mm insert. Which one do you run normally and also I am going to be running 30% nitro in this engine do I need another cooper O-Ring to run this fuel?
Thank You
Michael Johnston

6mm for small tracks
7mm for medium to large tracks

It's shimming for 25%-30% from the factory.

If you are using a new pipe, it's recommended to clean it with break cleaner before using.
