The fill cap cover is plastic.I do not think a bad poppet would affect that.The problem has to be in the fill port check valve.
Both of my M-Rods shipped with a protective cap on the muzzle. I just assumed that it was only for shipping, so I tossed it back into the box.Hunter
Thanks Keith, any tips are welcome! Poppet is back ordered so I’ve got some time to plan. Wife just got home after breaking her hip, so I’m pretty busy looking after her now anyway. Thanks guys for the feedback!!
James,Order more than one poppet. (If you have a spare, you will never need it.)Get the o-ring for the valve too.A bunch of 118s.
