Interesting thanks, I imagine mine would start 31 and the 3 is missing on the model number.

RE the wires coming out from the engine, looks like a red and white wire, and also a black wire, going in to a white plastic two pin plug, but the black wire is not connected to anything on the other side of the plug so am I right to assume this is the lighting coil wire!

The other wires beneath it in the photos are to the carb fuel solenoid on the other side of engine. I had flushed the fuel system out, was clean, runs like a dream apart from backing off of the throttle. Locals always moan about poor quality unleaded fuel we have, but I run a diesel van so only buy petrol for my mowers! But yes, possible air leak, I did have to replace two lengths of fuel pipe due to perishing, (plus the tap and filter of course).
