Are you running progressive linkage on the carbs? If so are the outer carbs set up as secondary carbs? It sounds like it might be over loading up with fuel. With progressive linkage the two outer carbs should not be operating at idle. Try disconnecting the linkage and check that your outer carbs are not part operating. A quick test is to put your hand over the intake of the outer carbs to see if the are sucking any air. The engine should run fine on one carb and then you can add the secondary carbs once you get it running right. Hope this helps.
