Correct. 1 is vacuum to run the petcock. 3 is the fuel line from petcock. The vent tube hooks in to a couple of holes on the side of the intake runner, keeps it out of the way.

Can you run through that again?? I thought 1 is the main fuel line, line running from the tank to the carb and putting fuel in the bowl, 2 is a vent line, and idk what 3 is, that’s why I’m here, lol.

3 is for sure a vacuum to the right side of the petcock. 1 goes to the left side of the petcock which does feed into the bowl. 2 just a vent that sits in the frame.

Interesting. I’ve got an Amazon carb the dude who owned the bike before me put in, and when I plug the vacuum line (#3) it starts ti run a little better, but if I put a line to the peacock from it, it won’t run at all. It pulls fuel through the line, is it supposed to do that?? (If I need to make a new thread lmk)

What is the peacock turned to Pri or on?

Is this is different pic, or did I screw up the numbers? Sorry if I did.
1. Fuel line to Petcock
2. Vent Line
3. Vacuum to Petcock

gotcha. What does the vacuum line do?? And will it hurt to plug it??
