how to use check the float to see if it is right.

how do you measure and what should the measurement be for ac 400

thanks

 

I simply remove the carb, remove the floar bowl, turn the carb upside down, and look at the angle of the float arms. I set mine to parrallel with the carb body.

Then hook the fuel line up to it, and while with the float bowl off, and still holding it upside down, you should see fuel coming out of the float needle. Let it fill up until it shuts off. If the fuel spills over the edge of the body, adjust it some more. It should shut off at about half the volume of the float bowl.. Hope this makes sense.
