the filter should have been soldered to the valve body you can resolder it of make a new one with fine brass mesh or... leave it out after cleaning the tank completely........ and install a substitute such as a round button filter between the valve and the carb inlet . they work fine on lawn tractors so should be ok on a small JW fuel flow wise
filter or no filter the motor should run anyway. filtering is just a necessity when dirt is present....
