Emissions help

Ha ha its getting a little tense here fellas I do really appreciate the help and I just ordered a digital timing light with tach so I can adjust and check both my carb and timing which probably hasn't been done in years as I believe it sat outside unmaintained for quite sometime before I bought it.

The carb I have on it I don't think is original as its a 1945 Holley and I think the 67 had the 1920 so any tuning tips would be great.

And Dan thanks for the links and the timing answer and 67Dart thanks for feeling my pain with the whole situation.

My Co2 at idle was 5.4% so .4 over the limit hopefully a good tuning and I'll be ready to roll
