Dear all,

I just got a new WT391 walbro carb. Now I have some questions.

1) it has two brass nipple, one close to the LOW/High needles and another on the oposite
side. So, wich one is the gas intaken? What is the other nipple for?

2) on the botton side, the side where I will attach the adapter, there are two small holes
one each side the venturi. one of them is blind, on the other, there is a very tight hole,
is there any problem if I close it with the adapter or do I need to do something about this
small tight passage?

3) Does this carb uses any connection to the engine pressure, ir order to make the carb pump work?
