I've got a Magma/Star sizer with the OEM heater and air cylinder. Using Magma lube.
80 psi air pressure. I get lube out of the side plug, to and through the die, but get no pressure from the piston/cylinder when the handle is cycled. The return spring is completely compressed, but there is no pressure felt from the lube being pressurized. Lube groove is not filled out.
Any ideas how to correct?
