If it really only has 800 hours (assuming on a rebuild) and hasn't sat too long, it could be a great engine. Most of the parts
are interchangeable with the 108.
I'm in the midst of repowering from a 107, somewhat regrettably. It was great and ALWAYS started very quickly (on about the 2nd chug), even after sitting several months. My problem was a cracked block that I attribute to a bit of neglect before I inherited it. If it wasn't for that I think it would run for many more years.
That being said, if you need any I'll have some spares and whatever comes off the engine available if anyone is interested. I do have a newly rebuilt set of spare injectors, plus a brand new (unused) heat exchanger
(mine is the vertical one just in front of the injection pump).
Good luck and I hope she treats you well.
