Well I got the new carb on.It starts and idles fine ,when I give it gas it spits and sputters.Is there a fuel or air adjustment screw,is there one for fuel and one for air or just one? where would it be?After a few minutes of warming up,it seemed to be running fine so I took off riding,made it about 50 yards and same old problem,it acted like it was running out of fuel.New carb ,clear fuel line,new filter! CONFUSED and PUZZELED!!!!!

There should be a single adjustment on the carb, called a pilot needle (not to be confused with the pilot jet), usually at the bottom of the carb. It should be set a certain amount of turns from seated position. On a stock 660 OEM carb it's around 2-3/4 to 3 turns out (if I remember correctly).
Have you verified float height before installing the carb? This could give you similar results as you got now.

Was this a "new" carb, or a new-to-you...ie good used carb? I just installed a brand new carb on my 04 Bruin 350 and it runs like new....no issues out of the box.
