Last year I took my 78 to a small service station on about 40th and Federal. the guy opened the hood, put a wire on #1 spark plug, placed the sniffer in the exhaust, let it idle, pushed the spring on the carb to get a slightly higher RPM, said you passed. He gave me the paperwork and I was gone. This was NOT a Colorado State station, but a small business that can do pre 81 I believe? It worked very well for me. I will be back in April when I need to renew.
