Hello,

I purchased a used ATV and there seems to be a few things missing and not connected correctly. I normally work on boat motors, this is my first time working on an atv, so I'm a bit of a newb this is comes to this stuff.

I took off the carb and cleaned it out and noticed that there are seems to be a hoses missing. This is the carb:

in the picture a hose goes from the bowl to the top of the carb, so where does the gas line connect to? Also the two screws on the site ( one large and one small. The large one seems to adjust the ideal speed, what does the small screw do?

thanks for your help!

 

the gas line should be connected to the port on the side, and the line coming off the bowl is just a drain off line for emptying the bowl on carb.
large screw is idle and the small one is air mixture
