Thanks for the replies. I live in Tennessee and in most counties they require emissions testing for vehicles 1976 and above.
The reason for the fuel accumulator and warm-up regulator was a cold and hot start problem. They cleared it right up. I guess I need to take it in and get the mixture adjusted. I have noticed I am getting bad fuel economy, not that these cars were great to begin with.
