Bought this Viva off of Paul on here, he fitted a Weber 32 ICT carb which was jetted for the 1256. It is running very rich and sooting the plugs up, even after a180 mile drive. It used nearly 3/4 tank as well. Using a colour tune winding the mixture screw in or out is doing nothing, the engine speed doesn't alter and it stays bright orange. The engine is also hunting. If I rev the engine the colour tune does change to blue or blue / white but not a bunsen blue. Unfortunately at present I am out of ideas. It has electronic ignition although I think the distributor cap carbon is worn so I will replace that. Any ideas or help would be appreciated.
