Hey, my car sems to be running like totaly s***!

Im sure the timing is out, we done the timing by lookin down at the big pulley that the fan belt was attatched to, and aligned the small mark on the pulley up to a plastic lip on the timing belt cover, accoring to this the timing is spot on, butthe engine runs really lumpy and doesnt have full power, it seems flat and low down in the revs under load there is a kinda rasp farting out the back box.

But, when i advance the timing from the mark it seems to run much quicker and all i hear is powerfull induction noise and it seems alot more like what it shuld be.

Can somebody explain exactly what i should be doing to get the timing spot on with a timing lamp?

Cheers!

Oh, and what do the small screws on my throttle body and the plastic one on my jetronic afm do?

:d

idle control valve on the inlet justs let more air in to alter idle..
airflow screw is to do with the mixture but only alters it ever so slightly... this will alter idle in most cases to..
