1990 Chevy TBI runs very rich

Hi guys,

Recently I got my 1990 Chevy Suburban imported from USA. I like it very much.
As every old car, there are some problems with it.
It is SBC 350 with TBI.
First, it runs very rich (at least I think so). I have to pres accelerator to start it, there is black smoke, very noticeable gasoline odor, rough idle and it often die on D or R.
I plan to buy TBI rebuild kit but rockauto supply two kits, one for TBI100 & TBI200, the other for TBI220 & TBI295.
How can I identify what TBI is in the car?

Also, I will be very grateful for any tips and suggestions on what to look or set in order to get proper operation.

Thanks a lot for your help,
