I have an 06 bruin and i got a jet kit for it but the instructions said to set float at 13.3 mm but it does not say how or where you measure it does anyone know.also how do u get the plug off the air/fuel mixture.

 

In order to access the a/f mixture screw, you will have to take a 3/32 drill bit and gently drill through the plug. You want to go easy as once you drill through the plug, you don't want to push through to far and damage the head of the a/f mixture screw. Once drilled through, take a sheet metal screw and use it to grab the plug to gently work it out.
