I have a question I just rebuilt my carburetor my Jeep starts runs for a few seconds and then shuts off. I have to use about 3/4 choke but it shuts off no matter what I do. I'm between carburetor issue or distributor I also rebuilt that. My grandfather tells me that when I pumped the throttle it should squirt fuel. I think this one runs off of vacuum if I'm right and that would only work while it's running.

Sorry I missed the comment. I doubt it is the pump. More likely just a lack of fuel. Check the needle & seat. See testing here: www.carburetor-parts.com/test-needle-and-seat. Could also be a vacuum leak.

I thought the YS was a side draught/draft?

[@MikesCarburetor]

Nope. Looks like that because of the top air inlet.
