Dear Kelly:

To be sure the diameter is no longer what it used to be due to rust but it was a calibrated orifice

I would try heating the hole with a propane torch, then take it to a local place and blow compressed air through it.

Also, wash the thing out with detergent and water, rinse with alcohol, dry with a cloth, then immediately rinse with brake fluid. This will remove gritty abrasives that will damage seals.
