Hi there, I have inherited a very well maintained Ransome Marquis Mark 4A petrol mower.

I can't seem to find anything about this model online and I really need to know what petrol I can use in it - I know if it is a four stroke engine, I'll be fine with normal unleaded but I can't tell if it's a 2 or four stroke engine.

Any advice would be very much appreciated.

Thanks in advance.
