Will an ACS 13T X 3/32 Crossfire freewheel fit an All-City Standard 130mm Hub? Will an ACS 13T X 3/32 Crossfire freewheel fit an All-City Standard 130mm fixed/free Hub?   I am attempting to setup a goldsprints setup using a very large front ring and a small rear freewheel. I'm not sure whether a freewheel this small will thread on to these hubs.
No. Freewheels that small use a smaller diameter thread intended for BMX hubs. The smallest freewheel you're going to find for that hub is a 15T. I believe ACS makes one in 15T called Claws that fits a standard hub. Cheap and it works.
