what does the mixture screw do in the carb, adn how much should i turn it

 

it changes wether it is rich or lean. i think it should be around 1 turn out, but i truly have no idea. i think if its too far out of that rance you will need to change jet size. i've never messed with it, i'm jsut saying what i've heard. i could be wrong also.

 

From what I've been told the mix screws function depends on where it's located.

If it's on the engine side of the carb then it's a fuel screw, turning out means more fuel. If it's on the filter side of the carb then it's an air screw and more turns out means more air.

I asked this question about my Warrior on here not long ago .. some time earlier this week I believe .. or late last ..

I'm in the process of rejetting now ...
