Great engine, Tommy! I have a stainless version and when I got it, it was all seized up as someone spilled a Coke or Pepsi on it. I washed it carefully and it came to life nicely. I forget what the model number is, but if you can get you hands on the Kontax engine with a 6” displacer, you’ll love it. Sometimes I sit in the recliner and just let it run on my stomach. Lol
In the photo, the red Kontax is the normal sized LTD engine.
