I just recently bought a '65 Rambler American 330 w/ the 196 and Flash O Matic auto trans. the engine runs fine, but the Carter RBS carb is a little screwy, it will start fairly easy and idle fine cold ( fast idle ), after it warms up a little, releasing the choke will cause it to idle irraticly, flood up and eventully die. the idle speed screw is all the way in. I know it has to have somthing to do with the float and the needle and seat. car is pretty much drivable other than having no idle capabilaties. I have an old " Jiffy " kit for the carb that I will put in it, anything I should watch out for when rebuilding the carb?
