Facing two problems since the last couple of days:
1) car is apparently running rich. Even on a cold start, it starts immediately as if someone had just driven and the RPMs stabilise quicker than how they did last week. It happened all itself. i didnt fiddle with any screw, carb etc etc.
2) the accelerator/sudden jerk issue came up again. So it's like: you press the accelerator half way and the car accelerates normally. just a little more push amd there is a sudden burst of power and the car suddenly accelerates. It then gets normal the next second. Sometimes I experience it on idle as well. Standing at a signal, if i rev it half way, the engine responds almost normally. just a little more push and a burst of power.
