Always one bolt....
All the rest of the bolts came away easily enough including the back flanged bolt, but I've managed to snap the head off the front 6mm flanged bolt (the central one). I'd hoped that the only threaded part of the bolt would be into the cylinder barrel, and that I could get the head off and then sort it, but the head seems stuck fast.
Does anyone know if the corrosion is just being stubborn, or if the the head and the barrel parts are threaded? Any help gratefully received.
