Ok i soaked my carb in dentured alchol, set my carb setting back to stock and i still have a problem. The carb will not let fuel in. I take the fuel line off the carb, put my finger on the stinger, and pull. My result fuel goes all the way threw the fuel line like it should. I put the fuel line back on the carb and it will not let fuel reach the carb. Can someone help me?
