I had the reg sweet spotted before this started but I did tear it down and clean/lube it. I have tried increasing pressure and decreasing pressure etc.
It really seems to be something with the Valve assembly. Everything looks to be good to go however. Fresh O-rings and lube. Stem looks clean as does the cup seal and valve face.
At this point im looking into replacing the cup seal and or valve in case there is some damage that I am not seeing. However I need a push in the right direction. I was looking at a valve assembly from a Rex Type R . Anyone know if these two are compatible. I think Odyssey had a Fasor style marker also at some point? I missed out on that whole age of markers.
