    Wheel Balancing Using A Liquid

    Much has been discussed about using beads to balance the Model A's wheels. However, I cannot remember seeing any discussion regarding the use of a liquid to balance the wheels. Pros Not abrasive like beads; Does not clump like beads; Easier to install than beads; I am guessing a liquid is less...

    In the air inlet throat of the Zenith carburetor, there is a tiny hole in the bottom of the casting just inside of the choke. My guess is the hole has a diameter of 1/32". What is the function of this hole? Is this tiny hole in all Zenith carburetors? I think it is a gasoline drain hole. I will...
