Carbs fuel system.

My banshee is starting ruff as well was running ruff. After running for a littel while it stalled and would not start up. I played with the choke and it finaly started. It seemed to only start up when i had the throttle open. It would not idle at all.

 

When I try opening the chokes one stays up and the other wont. Are the chokes supposed to stay up or supposed to stay down. Whats the best way to start the engine. with them up or down? are they supposed to saty down until the engine is hot and then they open automaticly or the other way around ?

 

The Fuel line coming up from the bottom of the carb (Bowl) into the throttle body shows the gas coming up a little less then half the length of the tube. Showing that theres air in side. Is this okay? asuming the gas is feed to engine based on gravity it should fill the entire hose up. Right? And the gas valve is open.

What are you running for carbs?

Well They say sunwork on the side. Thats about all I no as far as type goes. I bought it from someone who I can't get in touch with.

Yeah its gonna be hard finding out what type. It dont have that black cap on the top by the throttle cable. I'll try and get some pictures of it. each carb has one screw/spring adjustment. one black choke. two tubes one coming from the gas and entering the bowl, one exiting the bowl and going up to the top of the carb were the air induction is into a valve with two conectors, one is caped off with a rubber piece . pretty tight.they all tubes look like nothings flowing through them even when the bike is running. I was successfully able to start the bike idling it with chokes down while opening the throttle for about 2 mintues then it shut off.

Those tubes going up to the top let fuel in at fuel throttle. It adds to the main jet. At least thats what I'm thinking.

any one know if there should be air in the lines ?
