Incredible 
. It's just an engine, time and money - nobody died - no need to get upset!!
I posted to get thoughful insight and I got that - and little bit more. I now know what to do - thank you all for your help - let's leave at that.
Although it's frustrating, it's really not that big an issue. The engine is comming out tonight, I'm stripping it down and sending everything out for balancing. With a little luck I'll have everything up and running (smoothly) in a couple of weeks. The weather is still really bad in denmark so I'm not missing quality street time - that's good
! (for me at least).I admit it may have been naive to think that the engine builder would always balance the crank - not the flywheel. If the engine builder was still in business I would have asked him - and if the original flywheel was available I would have used that to match balance. I don't have those options unfortunately.
I was looking through some old pictures of the engine from when I changed the oilpan. Looks like quite a lot of weight was taken out at both ends of the crank.
