Taotao 110cc.

I have a 110cc taotao..It has a line that goes from a nipple on the air filter ( which attaches straight to the carb) and runs down to the crankcase. The four wheeler will start if I have the line off but as soon as you hook it back up it'll kill it a few seconds later.. The line cane from the factory like this .. I can't leave the line off due to the nipple in the air filter and if you try to plug the hole in the air filter it will die..Just wondering what might cause this?

Welcome to the forums.

That sounds like a crankcase vent line. The fumes are drawn up into the air cleaner. When the engine starts it draws them in and burns them. If allowing extra air into the air cleaner allows the engine to run then either something is blocking air from getting into the air cleaner or something in the vent line is plugged.

I was looking around and found this.

Have you tried installing a new air filter?

Allowing extra air kills it

Did you read the link I left you ?
If letting more air in stalls the engine..... then there isn't enough fuel. Too lean.
