Carbed cars don't have a TPS. According to the Haynes manual here is the list of problems if the "engine lopes while idling or idles erratically"

-vacuum leakage. Just check all those little hoses under the hood to make sure none are cracked, especially at attachment points

-leaking EGR valve. here's how you check it: bring the engine up to operating temp, in neutral allow it to idle for 70 seconds. tap the gas appruptly to bring the engine up to 3000 RPMs. The EGR vavle stem should move. I'm guessing you will need a friend to help you with this.

-check the fuel pressure

-leaking head gasket

-timing belt or pulleys worn

-camshaft worn
