Ok i have a problem. I need to change where my thorrtle arm is. Not reverse the carb just move the arm. The are on min is metal. Please help thanks.

So what is the problem ???????

I dont know how to flip the arm over so it faces down at idle.

There is a screw. I don't remember if it is in the center of the the throttle arm or weather it is a set screw on the side but regardless, just loosen it , reposition the arm and retighten it. You will have to make sure it will open and close the carb barrel after you reposition it. Take a good look at it you will see what I mean. It's very easy.

Ok thanks a lot. I just moved the arm and its in the place where i want it.
