You need a special idle adjustment tool, which you insert through the
top of the dashpot to change the mixture. Yours seems to be pretty rich
-- turning the special tool counter-clockwise will lean it out. Do so
in quarter turns, and until the idle does not change when you budge the
carb piston upwards ever so slightly with a screwdriver, and the air
filter off.
You need to get this straightened out -- fortunately, it's not
difficult.
