I need to check my CAC and see if it is responsible for my probable un-registered miss-fire\backfire .. But the search button did not find what i swear i remember reading that you could determine the depth of crap in your cac ..
anyone have a link? or am i crazy and someone simply shoved a mighty-vac tube into one of the sort off accessible ports?
