Lots of things could make it sluggish when you gas it. Has it had a basic tuneup lately. If not... New cap, rotor, wires, plugs and set the dwell and timing. If that does not help I would be sure the accelerator pump is working on the carb. Look for any bad or unplugged vaccum lines also. Just some ideas.
