I have repeatedly pushed the valve stem back into the stem and try after try am failing at thumping the valve stem out to where I can grab it.
I have pushed it through with a piece of bailing wire; each time blowing out all excess slime then will line it back up, thump it 2,3,4 times and it will not come back out. How, in every video I watch, is it only taking two thumps for the valve stem to come back out?
