is there any other O-rings or things I should order to rebuild and tune my x-valve and retro valve that are not included in the parts kit? both have lvl
It was hard for me to understand at first. But there are 2 sets of asa screw holes. One set on the relatively flat edge and one set on the rounded end.
When I put in a new o-ring I either throw it away or put it in my used o-ring bin. Not sure what I did with it in this case.
