Cloudy Radiator Coolant (After Flushing)

nm9stheham Yes, I spoke to the guys that rebuilt the carburetor and they say the vacuum reading is normal since it seems the engine has a higher cam. That's why the vacuum stays between 9"-11" at normal idle settings. It does dance around a bit, but in a healthy way. It's been a bit of a guessing game, but it seems that most of these other problems were caused by it sitting for so long after the rebuild like how you suggested with the cooling system. It's a time capsule, but that's what's been part of the fun!
