Flooding is down to either a worn or faulty needle valve or excessive fuel pressure , should be around 3 psi .was it the genuine volvo emission carb or a general CD175? Adjusting the needle will have no effect on float level . you don't have the Pierburg/ Stromberg carb with the flat metal float chamber base do you?
