Hi guys & sorry to bring up this topic again..
A newbie here. Anw, by reading about how to do carb tuning, i got a ques to ask. Im riding a Krr150 and has done some mod on the block, piston and etc... So my ques is, i jz bought a new racing carb size 32mm.. So before changing the main jets and all, wat do i do 1st?
-Tighten or loosen the fuel mixture 1st?
-Idling screw (tat control the throttle valve heights) shld i tighten or loosen it 1st?
Cuz i was thinking, b4 selecting the best main jet and pilot jet, do we need to tighten or loosen all the screws 1st b4 proceeding to the next steps?
