Miss might be timing messed up (stretch chain, mistimed, distriubtor needs cleaning/adjustment) or something else ignition related (worn cap, rotor, plugs).

Or the vacuum pod coming on too soon at idle providing too much advance. The vacuum pod needs to be plugged into the ported vacuum fitting on the carb so it is not apply partial advance. If you have plugged into the manifold your getting full advance at idle. |
