Not just on 'cats ... it is a hooded ssb style Bing like 1/12/1670 or 1/12/325 or other similar 12mm two stroke atomizer wide rectangular bodied Bings with a hood shaped cowling and wire harness clip that came on several saxonette-based mini's including Arctic Cat, Coleman, Fox, others, also on a handful of Jawa's. A complete serviceable unit or the main body with internals would be awesome, but I need at least the slide needle and the float assembly components. No intake necessary, but the carb itself and the intake adapter flange might be useful for some porting efforts i have in mind also. attached example pic. email.
