Ok. My friends bike wont idle. It's a cobbled bike. Anywho. I noticed some one of those brass tubes on the side of the carb is broken at the top where the choke stuff goes. Ok. No biggie. He has several spare carbs laying around. I removed one of the brass tubes from a "dead" carb and I am wondering, what do I seal it with at the top? The Bottom looks pressed fit. No biggie there, but the top part looks like some sort of sealant is on it. What do I use to seal it? Thanks guys!
