A-25 fuel tank cap

[Goman]

Hello all,

Probably something I should have asked before I started messing with it. I assume the screw at the bottom of the inside of the fuel cap is an adjustment for air flow. I managed to get it to turn but seems not to do anything (stripped?) I can blow through the tiny hole at the outside top of the cap and get some air flow but not sure if it is opened enough to keep the fuel going. Should I try and drill out the screw and maybe try tapping in another? As always thanks for you alls help.

It’s not really an adjustment, it’s a valve to let air in, but should close if the tank tips or fuel sloshes around.
