Hi everyone, can you possibly help please. The panda 45 runs and drives but i cant get rid of a bad misfire . The car has liquid dripping out of the exhaust, and every now and then there is a pop and a little bit of white fumes comes out of the exhaust. I have tried to adjust the Weber carb but it doesnt get rid of the misfire, and i have checked the spark plugs and they have a bright white centre post (cant think of the name). Can someone help
