The Farmall Cub is a vintage farm tractor that was, at one time, one of the leading brands on the market. Although they are no longer produced, there are many collectors and enthusiasts who buy, sell and use Farmall Cub tractors. If the Farmall Cub runs poorly, or dies when the throttle is increased, it is a sign that the carburetor may need to be taken apart, cleaned and rebuilt. This process can be accomplished in an afternoon.
