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.

If you`ve definitely got all the bolts out then it`s just being stubborn I reckon.Sometimes when they've been on for a few years they do stick to the base gasket.

they do get stuck, there is a built in recess for prying head off, one each side.

Thanks for the replies all - an update - managed to get the head moving relative to the barrel, so the gasket has now parted company, but the front bolt is still solid tight. There's no sign of it lifting at the top where I sheared the bolt head off, so either it's corroded together at the like concrete, or the stud us threaded in both the head and the barrel. I'll post a photo tomorrow night when I can find the USB lead for the camera!
g'night all

Bolt is only threaded into barrel but corrosion will have filled the hole----wait till you try and get the barrel off!!!
Lots of WD40/Plusgas and some heat from a small plumbers torch will help
