hey building my first moto on a beach cruiser... Finally found someone that sent me a kit into cali but question is do you need a gasket for where the carb connects into the engine and if so i have to options in my kit a metal one that fits perfect and then a material type one that is slightly smaller and has room for movement? second question is my fuel filter was cracked to say the least, can i just grab a new one from napa auto parts that is similar but a little bigger or do i need the exact same one.....sorry if these are retarded questions. thanks for the help
