air bleeds

What does it mean when I cover my idle air bleeds with finger and the idle speeds up?

It likes it richer. smaller air bleeds help it get fuel on the idle circuit.

so does that mean I need smaller air bleeds

Maybe. Or the idle mixture screws are misadjusted, or you have a vacuum leak, or there is a pluggage or partial pluggage in fuel transfer portion of the idle circuit. It is simply telling you that the air to fuel ratio is lean, not necessarly why.

Maybe. As stated, make sure your idle mixture screws are evenly set first. Air bleeds control air. Larger bleeds give a leaner mixture, smaller bleeds give a richer mixture. Idle air bleeds, the outside ones, will affect the idle mixture up to, generally around 3000 rpm. The smaller high speed bleeds will affect the higher rpm fuel air mixture. The cam and carb size determine the rpms at which the bleeds affect. This is all "generally speaking". From what you have discribed, the carb is running too lean for some reason.
