I tore down my 066 Sunday afternoon, I got it in a box missing a few parts maybe I'll be able to find everything. After tearing it down I'm not sure it will be worth it but I'll hunt some used parts. The Jug and slug are toast the crank also.
Here is a pic of the big end bearing if you click on it and get the bigger pic you might see the bearing cage is broken in more than one place.

Here it is all apart, I got the bearing and seals out after this pic, Its going to take some parts to run again but I hate to give up on it.

Now all it needs is more clean up, more pics as I go. Thanks for looking.
