Also I'd say advancing your timing on distributor +2 degrees (you'll still be within specs) will bring your HCs down.

Yea it was warm when I got there and he warmed it up before testing, But timing is something that I will look at. I might just rent a timing gun from Autozone to check the timing to see if the previous owner messed with it or not.
