Hello, after changing the cylinder head gasket and the timing belt, the car jerks and has no more power. When the timing belt was put on, the markings of the camshaft wheel, crankshaft wheel cursed with the markings on the plastic cover. The ignition distributor is also on the marking. In the windows (why two, starter sniper and flywheel) of gears I found no marking!!! What do these look like, are they notches or some kind of pins (of which I have seen two of them), when everything is on O.T. must be seen the markings in the window? At the distributor we have made no changes! The engine jumps well, but without performance. Do I have to adjust the ignition if yes why and how? About help I would be very grateful.
