Ok guys, got a weird one here. I have a Honda GX160 with a 2:1 gear reduction wet clutch on my Bluebird BedBug Bed Edger and i noticed that when i engaged the clutch i see oil coming out of the fill cap (pin hole in the cap). Is it possible that this fill cap is from another machine or something? Never seen a pin hole in a filler cap and i'm wondering if this is right. I bought this machine used and just noticed it. Anybody know anything about these gear reductions i would greatly appreciate it.
