hi, my friend has a fm4 that he purchased a year ago.. it shows that it has less than 200 hours on the head. but we now can't fill over 120psi. it like just runs and runs and dosen't build pressure over that.. anybody have any ideas.
i think i need to rebuild the head.. does anybody have a rebuild kit for it?
thanks
