Incomplete finishing

Driving in VW 1302 Super Beetle this coldest morning proved the richer idling mixture, because in the atmospheric air condition below 0 degree celsius the combustion performance was excellent without any tendency of coughing or hesitating those were caused by lean mixture.
So, just a little bit opening of air volume adjusting screw opening, 1/16 counter-clockwise rotation.

About newly produced TOYOTA FT86 sports model, I'm going to check the description on 2 types of differential gear ratio, probably the same as SUBARU BRZ, because the constructors are same and the planner of these catalogs must be also the same?
However often I might repeat to consider about the relations between the diameter and final gear reduction ratio, the description is not realistic to satisfy the common sense at all.

As mentioned yesterday, the combination, smaller tire diameter and lowered reduction gear ration, and longer tire diameter and higher gear ratio would produce some completely different character on earth!
For the setting of general commercial vehicle upper settings are most unlikely.
So I conclude that the descriptions I pointed out here in the catalog must be misprints based on misunderstandings.
