When was the last year they made a Chrysler (not Force) 15HP. I have a chance to buy one in really decent shape. It has the original prop with no dings. Everything looks good. This 75YO fella really took care of this thing. Alas, there is 5YO gas in the carb, so I doubt it'll start without a little (lot of) cleaning up. He's not sure of the year, only that he got a good deal since he bought it new the year after they stopped making them. I'll probably pick this motor up no matter what, but it would be nice to know what year it is. Thanks.
