i have an older version of the fox 40 the one with the muffler that slants downward, i've been trying to reguvinate the motor and i soked the carb in oil becasuse it was stuck. so when i took it out i jiggled it a few times with the plyers and it became free(the throttle arm) but the actual opening in the carb does not move, i assume this means it'a broke and i am trying to get another carb or find a replacement. can anyone help me?
