I am looking for more info on the straight through carbs, specifically the small vent on the side of the carb which is only on the straight through NH type. I would like to know where that vent goes because when I blow air through it, it doesn't come out anywhere. What am I missing? Any help would be great. Thanks!
There are two vents on a straight trough.One is under the Data plate and goes down into the riser part of carb. The other is on the side and goes in(about 1/4 inch) and down into the bowl.Take bowl off and locate that vent hole. I just pass a stiff piece of wire through it to make sure it is open . The outer cap unscrews.
