Hey Chris.. you still want to use that OS 61 that I have? (for the Tiger 60) All you need to do is put in a front bearing, which I also have. It's the same engine that I had on my Tiger 60 a few years ago. Runs just fine, but as I said, needs that bearing replaced.

Meanwhile, you want an engine for the Tiger II? I also have an OS 46 and an OS 50 that I am not using right now, you are welcome to put either one on and see how it performs. You can decide to buy one of your own later on, this will be for you to test out and see what one you prefer.

Dick.
