Hi every master.

I know majority ppl will advice not to tune the a/f ratio ...

But, I just want to learn something ...

we adjust the screw out towards the firewall is for "lean" or "rich" ?

we adjust the screw in towards the carb is for "rich" or "lean" ?

In my opinion... that wont help much for the actual A/F ratio.
For carbs... it is related to the "jetting" setting...

If wrongly modify... teruk! Good luck....
