COmpression?

For those who haven't yet split a Dexta, it's a lot easier than I thought it would be. I put it off over the winter; cold being a good reason.
It took 2.5 hours to split. The clutch was dragging and the reason was a missing split pin allowing one of the three levers to lose its fulcrum point.
The thing that concerns me is that i can turn the engine over by hand quite easily using the flywheel. I should have thought at 17:1 compression ratio I shouldn't be able to do that. It's normally hard to start but it doesn't breathe much.
Any thoughts?

I've just had my engine rebuilt. It's pretty much impossible to turn by hand on the flywheel with injectors in. With injectors out, just possible but painfull, hence I've purchased a 3/4" drive and a 1.5/8" socket! Note not all sockets of this size fit my pulley nut, but my cheapo chinese one does.
All the best,
Ben
