I measured the bore ,and that says 31 mm, and as the 91 cylinder bore was only 27mm, it really is a 240

Many thanks, the right cylinder has some sort of alu disk, preventing the piston to hit the cylinder head! imagine that I guess manufacturing standards on these where not so high?

Hello everyone, I have a few questions regarding the UK made Magnum 4 stroke engines. I searched the internet, and found out that they also manufactured a 120 size single cylinder engine. A model engine collector told me that they also fabricated a 240 V twin, besides the 182 v twin engine. I assume I have a 240 v twin magnum, the place where normally 182 v is mentioned on the engine housing, is machined blank.. My engine has black cylinders, and red anodized cylinder heads. Also a 'US' type prop hub ( much bigger then the normal version) Could anyone enlighten me with some info please?
