I have problem regarding the tuning of r150 stock carb,.What is the correct mixture of Air/Fuel for raider 150 stock carb? thanks for answers

The manual says pilot jet 12.5   and the main 110     I'm running stock everything with  pilot screw 3 1/2 turns out  idles lovely at 1100 RPM

I believe the pilot screw controls fuel  not air as it is on the  cylinder side (output)  so more turns out will give a richer mixture.

Sorry manual says  main jet  112.5      but I ordered  direct from Suzuki Thailand   with part number 09491-22013-000  and on the jet it was marked as 110 so ?????

they also say  pilot jet 1 3/4 turns out  and idle speed set to 1400 rpm   ( I think 1400 is too high )
