New: sealed carburettors for the Rotax Final

The process previously only applied to the engines, but this year, they are also the Dell’Orto carburettor, provided at the last moment by Rotax, which have been delivered sealed to competitors for the Rotax Grand Final in Valencia. Engine, carburettor and exhaust are identified by the same number on each kart.

It is impossible to open the carburettor, but the needle and jet are within certain allowed changes in the technical regulations. (A range of jet sizes for each category, for example).
