Keep the dirt outside from the carb: gas filters

When refueling, dirt can easily get into the tank unnoticed. And who knows whether the fuel tank at your regular gas station is cleaned regularly? To prevent dirt particles from making their way unnoticed into the float chamber and the narrow-bore carburetor jets, use a fuel filter with a fine-mesh screen or, better yet, a paper insert or, at the top end of the range, a washable sintered bronze filter. W&W Cycles offers a selection of fuel filters from Colony, Helix and Pingel.
