Only when warm and not consistantly I get just the lightest weep of fuel come out the main jet @ idle 750 rpm. Not enough to change the way it runs but its there. I tried float level, power piston spring, power piston adjustment, needle seat, I even swore at it. Its like vacume sucks it out or preasure pushes it. Its just a slight tiny tiny drip once every minute. Any thoughts? Its a mid 70s Q-jet on a mild cam 350
