Thanks for all the nice comments guys! I just scored a pair of rear fenders today (see my other thread), but I guess they are for a 70/100. I kinda thought they were, but for $72 I couldn't not buy them. Maybe someone wants to trade even up?? Anyway, the O is tucked away back inside and soaking in penetrating oil. I'm going to be out of town for a week, so I think I'm going to get it fired up when I get back to see where I'm at with the engine. Like I said, this is going to be a slow gradual project as I have a lot of irons in the fire at the moment.
Here's one more pic of it with my workhorse 149 (with the free wheelweights I just got for it as well as the $30 Brinly cultivators - It's been a heck of a week around here!!)
