Done that just mate, replaced the plugs even though they looked a healthy biscuit colour and had a play with the carb and made it run a bit leaner. Was a bit pissed off tbh its an old car and likes to be warmed up so i gave it a good blast on way to the testing station dropped it off at 10am and the didnt test it until 3 hours later so it would have been cold again
