Why do I need to drain my carburetor?
(Side Note: If you plan to store your motor for a while, you should drain the carburetor.) The gas sitting in the carburetor, if it has ethanol in it, will absorb moisture and “gum up” or choke the fuel passageways. When you try to crank the motor, the carburetor cant flow the gas properly and wont start or run well.
