Welcome Shawn, hopefully we'll be able to help you out.
If you're struggling to upload the pictures here - and if you're not easily able to re-size them - please feel free to try out the gallery (link at the top of the page - you'll need to create an account, the "Global registration password" is revealed in the Member's Only board), then you can put links in your post to photos there, or put URL links in to "in-line" the pictures. Alternatively, you could upload them to somewhere like Flickr or Photobucket & paste links to them here.
Also - it'd be appreciated if you could only post the one time, in the most relevant board (I know that sometimes it's hard to find the right one....). I've removed the duplicates for you, this is probably the best place for these questions.
Last but not least - if you can post the serial numbers of the engines, anything newer than 1952 has the engine type built into the serial number. Anything earlier than that, we'll need to know what model it is to figure out its age.
A post-1952 (pre-1970something) serial number looks (for example) like this:
1234ST1A7: That would be engine 1234, an ST1, with anticlockwise rotation, built in 1957.
Air-cooled diesels are likely to be LD or ST engines, probably off a dumper or cement mixer. If they're runners, they're good little engines, decent HP too. If they're not runners, they shouldn't be too hard to get going either, depending on how worn they are. Parts are reasonably available, depending on the exact type of engine & your location.
