Assuming you're getting enough fuesl, I think "pettybluedart" gave you the best answer.
While a trick carb is grea , you can make the best of what you got & in this case, again I think he gave you a good answer. I'm curious-what do the plugs look like? If it were me, I'd find a quiet place & launch the car a few times & immeditaely shut it off & read the plugs. Once you know what the cylinders are "seeing" you'll know which way to go with the carb settings.......
