34 ich i think its called ,or zenith 36 1v you will have to be carefull with yours as you probly will have the bolt throu the airfilter pan ,after 75ish they didnt do this anymore ,so basicly what i mean is getting a erly carb is going to be harder than a later carb,if you were to get the weber replacement there isnt much way of holding on the airfilter pan!
