On H twin and V twin engines that share a carb, it is common for one cylinder to run leaner than the other. Don Vogt and I talked about it before. When they set up the twins for pulling, it's not unusual to use two carbs. On a Harley, they found the same to be true. One cylinder will run just a bit stronger than the other. On a stock set up, it's not an issue. But in the pulling world, it makes a difference. I wouldn't worry about it Stan. It's normal. After a bit of run time, you won't be able to tell.
Get you're old timing light out again and check the flash....
