hi all, the regulator on my sabre lady anne doesnt shut off dead like my usual needle valve type but feels "spongy" and is not very finely controllable. before i take it apart, does anyone know if it is liable to be an o ring type as fitted to roundhouse r/c locos and therefore thats how it should feel please? anyone converted to needle valve with success? thanx, mart....
