I'm looking at buying an m115 engine and I'd like to ask about it as I'm not intimately familiar with it. Mainly where the model number is stamped on the engine and/or how to tell the difference in specific versions? What the compression should be? Also if there are any specific things I should look out for on them?

Yet another fake post, and this is the second time for the original post to be copied.

Here's the original post:

What is the purpose of this nonsense?
