NSS only comes into play when cranking. It just prevents from starting in gear, cant interrupt ign signal while running. It truly sounds like a carb issue, probably a vacume leak. Try spraying around the carb and engine vac lines with carb or brake clean. If the rpm picks up you have found your leak. Do this checking with the air filter housing on to get a true reading of a leak.
