This isn't 1500-specific, but before you start disassembling everything
make sure the jets are returning to the "full up" position when the
choke is released. They can stick in the "down" position, particularly
if the car has been sitting for a while.
Then check to make sure that the air filters aren't choked full of
paint dust.
Next, don't assume that the problem is carbeuration. Check the
ignition system, a weak spark can do the same thing.
Finally, don't assume that the guys in the body shop didn't fiddle with
the carbs. (There's always one know-it-all...)
To answer the broader question, if you're running dual SUs, the 1500
isn't significantly different from the 1275 as far as tuning goes.
