fuel smell could be either the filler neck connector corroded where it enters the tank so check this area. Also check down in front of the passenger side rear wheel area, this is where the fuel pipes come from the tank and are known to corrode there. On my facelift car there is an external fuel filter there too, not sure if it is on the pre-facelift cars like yours.

so an overfueling problem or something similar by the sounds of it, prob best to wait to hear from someone like Brianmoore or Ant.

Could be the setting on the air flow meter but don't meddle with it without advice as they can really be a pig to set once you start losing track of how many turns you have done to the screw. But could also be electrics like dizzy cap, rotor or a crap plug not firing on a cylinder properly.

An air leak could possibly also cause this problem so check the rubber bellow for splits and check breather pipes and vacum hoses.

good luck fella, probably something daft though
