People reading this thread may not recall it’s about a Bx…. and, while I’m sure you did not mean to mislead anybody…..your post did not include that tidbit either The point being that evacuators don’t work in all situations.no but on a bx they work fine, and bx is what this post is about, not L series or M series or MX series or LX series, although I think on LX's it'll work on those too. Probably a lot of B series as well.
