I think I got it. It was a vacuum leak on the intake manifold. But now it idles at 2000 rpm. Do you know how to adjust it? And it runs good for 10-15 miles everytime I take it apart then sputters and dies. I installed a 2nd fuel pump and its doing better. Also, where the throttle cable hooks up to the carb the nut was loose so I tightened it and now the throttle doesn't want to close?
