Ed. located the engine tag just where you guys said it was, did some cleaning and although still difficult to read, again using my wife's eyes found the following info:


M 121 B II

bottom line reads left to right

Motor # Engine #
121.921 10 020 921

the other number in the previous note was stamped into the block just below the valve cover above and between the # 2 and #3 sparkplugs--and that was the 121 01038 20

We did not see the 928 anywhere on this tag

am I any closer to the correct #??
