engine runs well normally but hesitates and mis-fires on quick acceleration or as soon as under load - then the car bucks like a stallion! Carburetter professionally restored, new rotor arm and distributor cap previously installed, points spot-on all to no avail. If i replaced all the leads and plugs, are there modern replacements like carbon leads which will perform any better? If the engine "breathing" becomes blocked is it sufficient to remove the oil filler and rear breather caps to clean the gauze areas, and if so, how best achieved - wash out in petrol and wire-brush?
Even if you have a later dizzy fitted the 25D6 its condensor will fit and these aere used on the really common 25D4 dizzy for Mini's Hillmans etc and Halfords stock them for a couple of £'s just do not mention "P4" just ask for a 1978 Mini 1100 with Lucas dizzy
