Without me looking this weekend, stick a magnet on to the carburetor air horn and see if it sticks. If it is aluminum it will be a Zenith, cast iron it will be a M-S carburetor. Sediments bowls should not be hard to find. I am going by memory but it wll be ashort style and the replacement Oliver number was JAS 841. I can probably chek that as well next week. That Continental engine is one of the easiest engines to get parts for there is.
