HI. just bought a k/b 3.5 and inneed of some info. The marine engine is in very good shape. Would love to locate a manual, and find out about the engine. The muffler is about one inch in dia. and has two vert. exhaust stacks. Have not tried to start, but the compression is great. Some one told me the model is a K/B21.
Thanks.
