Might want to rejet the carb for sea level. might be running lean at sea level with Colorado jets, which won't help with ping. Good luck. Too bad you left Colorado but at least you went to Texas and not CA!
So far I'm a fan of TX. They will let me register as a classic which is emissions exempt, vs Colorado where I was one year off (76 vs 75). I used to live in highlands ranch and had to get creative to keep it registered.
