Ok, I bought two engines and two gearboxes. It was just for having something to play with and some day get to run. The seller only had a 807 and a 697 with the waterpump in the right place, and I wanted the 807 because the engine installed in my car is build on the 807. I also wanted the 697 because it is like the original Europa engine (I know the Europa 697 is different). One gearbox is a NG1 and the other is the 336, which do not work, I can see it now, but I was in a hurry and I was curious to see the inside of it.
The 807 turns and the 697 does not. The 807 also have the most parts and I had the rest to make it complete. I will work on that on first.
Cheers
