Welcome, Zack !!!

I would also verify that the bottom of the tank does not contain water that may be flowing down into the bowls.
You can check that by draining the bowls and the tank (only some of the fuel), with the cockpit in reserve, into a glass container.

If while draining the tank, you notice that the flow is less than 2 c.c. per second, then the mesh filter inside the tank is partially clogged and should be blown backwards.
For that, you will need to apply vacuum to the small port of the petcock.

If the flow is good, next I would check that the vacuum tubes of the carbs and petcock has no leak, so there is a strong vacuum signal reaching the petcock.
