Is anyone familiar with a small 4cyl horizontally opposed OHV engine made by Chrysler,of about 600cc/37 cu in,and made to lawnmower standards...ie...alloy conrods without shell bearings,very small valves and weak springs, etc.?...I saw quite a few of them come thru the sales ,some even new/unused,but most partially or fully in pieces.....and wondered what they came from.....probably a genset....Anyway,came across a few bits looking for something else,and it jogged my memory.
