ok hear is the skinny...
it's an 85 gs. it wasent running good under 3k and didint want to idle under 1200. i need to take it to emissions so i rebuilt the carb.
now the idle will jump around at 1000 to 1200 for about a min. and then drop down and jump between 400 and 800 for a bit and then try to die.

that is with the shutter valve hose pluged becous it started shuttering. im thinking maby i've got a vcume leak that im missing.

eney ideas would help.

thanks.
