I am guessing you have a major vacuum leak. You say you have a "hollow plug" on top. If you are referring to the place where a tamperproof plug is supposed to be that is the spot to adjust the mixture screw. Make sure it is sealed against vacuum. The metering unit doesn't really do much at idle as the idle motor controls the amount of air, the fuel distributer is just putting the minimum amount of fuel into the motor. Check the 3 brass screws on the intake plenum are LIGHTLY seated closed and the idle micro switch is being activated by the throttle spool at idle. There is supposed to be a vacuum layout sticker on the underside of the engine cover.
