Running carburetor off a 1970's Chrysler 8 hp - I can't see where this wouldn't be identical to the ones fitted to the earlier 7.5 models and possibly motors like their 6 hp or 9.2 though jetting may have differed on that one, presuming it had same venturi [ie. throat] size.  Carburetor was manufactured by Tillotson who made a crap-ton of carbs for all kinds of small engines including several outboard manufacturers.  The motor was a "barn find" or "garage find" unused for several decades - of course the carb needed a cleaning but it wasn't too bad at all - the usual bowl clean and a blow-out with compressed air and the motor started right up.  I had complete motor for sale for a while with no takers so it's being parted - if you need anything I'll list it.  I'm pricing the carburetor to move and shipping is as cheap as it gets via Flat Rate Priority Mail.  Thanks for looking.
