Modifying stock super 9 carb

[Superstu]

I have an AC super 9 with a 70cc kit. But I'm trying to tune the carb and I noticed there is no notches on the neddle valve. Is there any way to fix this problem? Maybe put a different neddle in it or maybe get a neddle with notches and swap it. S help my cht is running a little hot.

Thanks stu

When no notches you get to shim it with very tiny flat washers. Yay shimming. Its a lot better to just rejet it a little richer.
