Good for you. You need to make it what you want or you'll never be happy. I was jes messin anyway.
Double check the tune on it. Timing, points dwell if it's got points, check the dwell anyway if it's electronic. There IS a spec. Put a vacuum gauge on it and make sure it's got a good signal. Smell the exhaust and see if it smells unduly rich. If you put the tools to it and pay attention, it'll tell you what's up.
