Hey rasmataz iam doing well just to add to this one what color is the smoke is it black?Does the miss go away when you raise the rpm's up?I would check the plugs you could have some bad plug's or a bad coil cassette.You can also spray carb spray around the vacuum line's intake gasket etc if the rpm's goes up or down or the engine dies there is a vacuum leak there.
