You have to modify the heat insulator block when using a carter 2100s. There is a vacuum port at the base of the carb. If you do not make a "channel" in the insulator block, that vacuum port is blocked and you will have drivability issues. There "channels" in the block for the Rochester B but they do not line up for a Carter.
