Hi, my name is***** will be assisting you.

The only adjustment that you may have on this carburetor is an air adjustment on the side of the carburetor. It will go all the way in snug and then back out 1 turn. This should give you a good starting place then you can fine tune from there once you get the engine running. The main jet is fixed and can't be adjusted.

Thank you it has been a pleasure to assist you.

There is a another adjustment point which has dots and a screwdriver slot
The one in the green box

That is the air adjustment, it is the only adjustment on the carburetor other than the idle screw adjustment up on the very top of the carburetor. I would never touch the idle adjustment without the carburetor mounted on the machine and the engine running. If it is wanting to idle to fast or slow you can then adjust it.

In order to make full adjustment on the air screw you will need to remove the black cap that is on it otherwise it limits the amount that you can turn the screw.
