I just had too replace the hose from the fuel tank too the carb on my auger, but now I have an air bubble in the line that I can't get out... I tried tipping the tank and have the fuel running through the hose as I connect it up too the carburetor but after trying too start the auger the bubble is back in the line. Could there be an air leak in the carburetor or maybe on the connectors where the hose is connected? Appreciate any insight.
