Default Adjusting fuel mixture. How do you do it?

1990 Audi 80 Sedan. Just wondering. Still seems like car is gasping for fuel at start up. Takes a few cranks to start and the motor shakes for a little.
Also. Sometimes I am having problems of loosing power. Sometimes I push on the pedal to take off and I go VVVVVAAAARRROOOMMMMM!!! Other times I go v...a...r...o...m... and I WAY less power accelerating like a snail. Any ideas?
Thanx!

Default there is a hole between the fuel distributer

and the air boot, 3mm T handle would get in there and turn a bolt that adjusts mixture

Default Re: there is a hole between the fuel distributer

Thanx! I kinda thought it was that but wasn't sure. I paid $55 to get it adjusted last time. I fixed some connectors going to some important looking parts and I think my mixture needs done again, I will do it this time. I can get a rich mixutrue tester from Autozone I think. It hooks into your O2 sensor some how. Any ideas on my vaaroomm problem?
Thanx again!

I have a new filter, I got it installed by a local car shop. They do pretty good work so i'm sure they did it right.

Also can be related to valve located on output side of fuel pump - keeps system pressurized when car is off usualy happens in warm climate - in Deutschland is usualy cool so I don't see this much.
