Intake size for a 1990 a3?

1990 tomos a3 with the sha 14.12. What's the OD of the intake and the ID if the carb? I have nothing to measure in millimeters plus I'm at work so i can't just go pull off my carb and measure it right now. Need to know the size so they can send me the right shim because either i ordered the wrong one or they shipped me the wrong one.

Thanks guys
