I took the motor apart about a month ago and dont remember this hole or taking a bolt out of it(almost directly in the center of the pic,.. just to the right of the middle 10mm baffle bolt)


.... Thats not to say that I didnt,.... I just dont remember.
I have the Honda service manual but it doesnt mention anything about it:

Did I forget a part or something?

 

Ok,.. so i figured out that its where a "sealing bolt" and washer go but problem now is that I cant remember what it looks like,... any help ou there?

 

Is it on the front or back of the motor?
