Sonya, stick with the SU's.
Your problem could be:
The butterfly shafts are worn in the carby body allowing too much air to get
in and tuning impossible.
The individual butterfly's are not adjusted to be matched at idle.
The mixtures screws on each carby are not set equally, so one carb is
richer/leaner than the other.
Check the butterfly shafts for wear, if they are sloppy they need to be
fixed as you will never get them tuned properly. If they are ok, disconnect
the linkage between the carbs and loosen the choke cable screws so you can
set each carb to idle, and its mixture screw, independently. When they are
individually balanced, reconnect the linkage adjusting it to make sure it
cracks both butterfly's at the same instant. See the Web sites on tuning
SU's for more info.
The twin SU's are really good if they are in good condition and properly
tuned and balanced. They should run for 50K- 100K without any further
adjustment.
