If a driver makes movements on the kart for fear of feeling pain, it means that he/she is not 100% fit. A driver does not normally have to change driving position on the track: sun screens and protections stored by the seat are there to increase comfort and allow drivers to focus solely on driving their vehicles.

The diaphragm carburettor allows you to adjust the carburation directly on the track, by adjusting the screws that regulate the high and low engine speeds. Over time, the diaphram inside it tends to lose elasticity, changing the carburettor settings. Drivers who participate in competitions usually overhaul the carburettor before each event and check its pressure after each day on the track. Amateur drivers only need to overhaul the diaphragm carburettor with each change of the engine piston, but it is still an activity that needs to be carried out.
