I recently purchased a 1978 G174 with a mitsubishi 2 cylinder. I have been trying to locate an air filter for it, have found some close matches at the auto parts store but too short. The local Kubota dealer refuses to crossmatch it or the headlights which makes no sense as the model of engine was also used on Kubotas. Is there any place to get one or am I going to have to rig up a new cannister?
