Hi

I have bought a Senator President FP, and I have some issues.

The pen doesn't fill, the ink flow out as soon as I get the pen from the ink bottle...make me thinking is getting some air.
The section and nib unit looks good to me, but when I have tried to remove the piston...It looks like there is the problem.

It seems like the ink is getting behind the piston gasket, and I cannot remove the piston. What to do?


Thank you
