    Hi everyone,
    My name is Louis, I live in Belgium (Namur). I am trying to revive a Ransomes 16’’ MK11 with a Ransomes 4 stroke engine, but some pieces are missing – piston segments, exhaust pipe, and a small screw on the side of the carburettor, and I don’t find any spares parts in Belgium. Would any of you have an idea of where I could find these parts? Many thanks to all and regards -Louis

    I am currently breaking a 36″ mower fitted with the Sturmey Archer engine there may be some common parts can you post photographs of your machine.

    Hello expeatfarmer, thank you for your prompt reply. I forgot to take pictures of the machine before removing the engine, but I could find pictures of a complete one on the internet (you see the exhaust pipe I am searching for). With regards the carburettor you see on my picture the small screw missing. Many thanks for your help.

    If you are unable to find piston rings it is possible to have them made. A UK company that can make them is Cox and Turner Engineering
    The missing screw on the carburettor looks like it is the tickler for flooding the carb. It may be worth contacting a carb company such as Burlen Fuels

    The engine is I believe a Sturmey Archer, the “screw” missing from the carb is as Charlie says a tickler plunger to flood the carb, the silencer I have is very similar I will take a picture.

    Yes, you both are right, it’s the tickler plunger. Thank you for both adresses, I’ll surf on their sites.
    Behind the mag chain (« Ransomes »), one can read « LSA 125 », I suppose for Sturmey Archer.

    Hello Andrew, do you mean the kind of clutch? I can’t see anything written on it…

    Hi all, I am very happy: I could find three segments, a spark plug and some material to weld an exhaust pipe. I will run in the valves next weekend, and look for the belt of the ventilator. My brother, whose venerable BSA motorbike sometimes needs to be repaired, told me I might find a tickler on Faked.com; let’s wait and see… The mower is nearly operational, after having slept half a century in an old orangery…
    See you

    thank you. But would someone tell me how to stop the engine? Up to now I close the fuel tap and wait for the carb to be empty, but there must be a more convenient way, am I wrong?

    There should be a metal tab on the side of the magneto at the points end near the clips that hold the points cover on. Press to stop.

    The only thing I find on the magneto is a kind of motionless button, screwed on another screw. There is a spring between both, but I don’t understand its role since nothing moves…
