73 scamp

First, congrats on your Scamp and welcome to the forum. What a great looking machine!

So the rich condition could just be a carb tuning issue. How can you tell that it's rich? Are you seeing black smoke from the exhaust?

Just as some unsolicited advice: check the date of manufacture on those tires. They might be totally fine but the make/model doesn't ring a bell and my first thought is that they might be old...and therefore a safety issue once you get the 318 pulling a bit better.
The carb has been set to about 12 lbs of pressure which is about 1 1/4 turns. It does have black smoke and the plugs are black. I just replaced all the plugs and reduced the jet size. The carb only has 500 miles on it so I don't think it's a bad carb. My theory is maybe a bad fuel pump that is increasing pressure?? Also, the tires are suppose to be brand new put on a month ago.
