Seems the MS 270 came out in 2003, but it had no 0 series predecessor. China parts ads are often filled with misprints.I can't find any information on the 027. I know it was made. I saw the pictures. An ebay link claims 56cc's. I am wondering about USA parts availability and any know issues/problems.
Thanks.
