I need to know the vacuum line configuration for this jackal ATV. I can't find any documentation anywhere on it. Was hoping somebody could give me a hand.
It starts up with the choke on but then will stall when the choke is turned off.

 

I don't know the model at all but if it has a vacuum line it will go from inlet manifold (or the carb, next to inlet manifold) to either a fuel pump or a vacuum operated fuel tap. All other tubes from carb will be breathers, except inlet pipe for fuel. One from bottom of carb would point down as it also acts as a fuel overflow, all others go upwards, but end pointing down to stop rainwater getting in.

 

This was helpful, this carburetor has some kind of a diaphragm controlled plate. And it has a choke button on the side. Do you know if this kind of carburetor has the button in for choke off or is button in choke on? Thanks for your response.

 

Chokes of the "excess fuel" type are usually out for on choke and in for off choke. A lot of ATVs have "constant depression" carbs where a diaphragm controls a throttle slide. Vac connections are usually internal drillings for the diaphragm but it is possible some may use an external pipe.

 

Thanks for all the suggestions. I think that ultimately the problem is that my jets are not tuned for 6,000 FT elevation.
