/6 carb help

been awhile but, pulled carb off other night finally and took top off it and it was very clean and all parts looked new so i removed a black plastic cap on needle valve(seemed it limit needle movement to me) and adjusted the float down to spects! put lid back on and back on motor been driving 4 days no issues doing great! float valve in kit i got was a size smaller so gonna see if i can return it!
