okay i think my problem why it want run right is it's fouling out the plugs i just put a brand new one in and its covered in black smoot. i tried adjusting the screw on the bottom of the car several times i started at 1.5 turns out went to 2,2.5,3,3.5 ect all it does is blow white smoke out the back. so what do i do? i've changed the needle clip setting currently it is on the secong groove from the top. i need some help cause i done run out of ideas. thanks, wendell.

 

try just adjusting your pilot jet, the skrew outside the bowl twords the engine. kawi uses kehin carbs so its a fuel pilot. skrewing it IN will lean out the mixture.

to try and solve your running rich problem adjust the pilot in so its only 1 turn out from being snug. let it run for a few munites at idol only, then turn it off and check the color of the plug. the pilot jet effect your fuel/air mix from idol to 1/8 throttel only. once you get it set to wher its not rich at idol you can move on to adjusting the clip possition or the main as needed.

hopr this helps
