Hi all I’m going to be picking up a 1969 Amphicat and was wondering what kind of air filter they have I haven’t had any luck finding one online or at Napa the original owner has been very vague on information and only sent me one picture of the 6 x 6. I have premixed gas and two new spark plugs I just want to get everything so that when I go to look at it I’ll be able to start it thanks
