does anyone have a baja 90 atv? been trynna get this thing to run well enough to ride. so i noticed there are 2 nipples on the carb, one has a fuel line coming from it and runs down along the side of the engine and just dumps, and the other has nothing on it. what i am trynna find out is if anyone knows if a vac or fuel line goes on the one thats at the top and if so where does it run to.

 

The one running from the bottom float bowl down along the engine is the float bowl drain / vent line that needs to be open to the atmoshere.
The other I think you are describing that points upwards along side the throttle slide is the fuel supply from the gas tank.
On the 2-strokers there is also a 3rd one coming off the side with the idle adjustment screw, and that one is the oil injection supply line.

Can you post a picture?

 

ill try to get to the quad this afternoon i moved it from my house for a moment. my fuel feed is actually part of the fuel on off petcock(fuel valve) i dont really think the one i inquired about is of much importance because when i look at a brand new pz16 carb i notice it comes with the line on it and allthat does is vent to the atmosphere.....
so without the bike actually running if i have the fuel valve "on" and press the throttle should i be able to feel fuel spraying if i open the choke and put my finger in there? also is the butterfly for opens when i open my choke suppose to only open as part of the choke or should it open anytime i hit press the throttle? because if its suppose to open as part of the throttle also its not doing so.. when i get through with this atv i might as well add chinese atv repair as a service that i offer at the shop.
