Hello, I've been having trouble removing the cylinder. I've done as the manual says and have removed what needs to be removed. The cylinder moves freely by about 4mm until it stops. It feels as though as though it's coming into contact with another piece of metal, but looking at diagrams and photos, there shouldn't be anything in the way. I don't want to break anything by forcing it. It's worth noting that the reason I'm removing the cylinder is because while I was removing the cylinder head, one of the cylinder bolts (marked by a screwdriver in the video below) broke off. Now I need to take the cylinder off to remove what remains of that bolt. I thought that bolt may have been the cause of my trouble, but the cylinder should just slide over it, shouldn't it? Thank for you reading.
