Thanks Wes!
I didn't realize I was being kind of vague...this is a new ballgame to me....but its the primary breather I was wondering about.
Its blowing goop from time to time & I was planning to just run a little hose downward (and hopefully AWAY) from the rear tire.
I just didn't know if there was some kind of usual fix, or if its a "whatever works" kind of thing.....
