Can anyone tell me what this nipple is for and if something should be attached or should it be plugged. Fuel was leaking from this and the carburetors when priming the bulb. I'm rebuilding carburetors as we speak.

The hose to the lower right of my finger goes to the top of the motor. Is that in the wrong place and if so what goes there? Thanks for the responses.

There is a piece of hose about 14" long that attaches to nipple and the other end attaches to nothing...

is there a top vent for the crank bearing, too? i forgot these motors don't have an airbox with a nipple. Whats the difference between a bearing vent and a crank case vent going to the airbox on smaller motors?
