The air bleeder bolt on my 79 2B wont tighten all the way down, allowing it to weep fuel from behind the bolt. It will tighten down to a point and then strip out. I looked on the $OR site and they list it new as discontinued and used NLA. They do list it them for the 82-87 B/3B used. Would this be the same..or even if i had to buy the hollow bolt as well..would it fit? Any alternatives? I have the spin on type filter.
