Guys,

Am installing a 3W 80XI single and am trying to figure out why the carb body has 2 fuel inlet nipples? Its not a Walbro carby (what I'm used to), Its a tilotson. One nipple is located at the bottom of the carb in silver (same as the carb case) and the other is gold on the side not too far from the needles.

Is one a breather of some sort? (one at he bottom??)

Any views on this would be appreciated,

Thanks.
