Agility 125 will not stay running

[dabumpers1977]

Hello,
 Please help me. I have a 2013 Agility 125 it will not stay running. It starts idils then when I give it gas dies out. I have changed spark plug, cleaned carb, changed oil, put gas in it. There is no fuel mixture screw on the carb. However I think this might be a vacume line issue. There are so many lines that I have no idea what goes where and to what. I have t's and a black small thing that almost looks like a filter that goes into a T as well. There is a line coming from that Carb that's a gas line that isn't hooked to anything. I need help!!!

You double posted for the same problem. I will guess you bought this thing from someone who could not figure out the rat's nest of hoses, right? You have a vacuum leak if you have tubing open to atmosphere. Start from there.

OK, that's a lean condition. The most common cause of a lean condition is a dirty carb. If you're confident that it is clean, replace your fuel filter next. Next, there is a vacuum line that attaches to the petcock at the bottom of the fuel tank. Make sure that's attached, and not cracked or worn.
