In reply to neil O'Brien:
I have a coleman peak 1 which I run on "essence C" as bought in French hardware stores. Its sold as dry cleaning fluid and works a treat. Don't use "essence F" though I did and it burnt a bit hot. I switched it off pronto as the pre heat element was glowing a dull coppery red in about 3 seconds flat,and that didn't seem right.
Worth a try for your MSR I'd have thought.
