Well, this thing is royally pee-ing me right off now. It was running and even dug a little hole.Then stopped. I have tried everything apart from actually finding the original spring links for the flyball / centrifugal governor. (they don’t seem to exist anymore)
Now the thing just will not start at all, it has a good spark, the plug gets wet so fuel is reaching the cylinder. it even tries to splutter sometimes.
I’m considering just selling it on at this point as I need a working machine to finish the garden!
Does anyone know of any working engines available that would fit this contraption?

The choke is closing yes, I do think that the issue is the slip ring and spring. The big spring pushes the slip ring away from the flywheel. I suppose this is then multiplied by centrifugal force when the pull cord is pulled.
But without the link springs to keep the slip ring in the hollow notches then the slip ring will be fully out all the time. I’m wondering if I could cobble together some link springs from old governor springs off an old lawnmower – I will try!
Thanks for all your help so far Wristpin, it is very much appreciated.

Perfect thank you! Figure 5.3 shows my first issue perfectly. It would seem that I am missing “B” and “D” the links and springs that keep the slide ring “C” in place inside the flywheel.
The million dollar question is are these still available and if so, from where?
It would explain the difficult starting etc as without the links and and springs to keep it in place, the throttle is stuck wide open most of the time.
It also explains how I was able to start it easily once I’d built it back up, but not so after I dug the hole as the slide ring must have spun around and now be in the wrong position.
1028503 is the engine number 1 being the first number indicates the year on newer engines, could this thing actually be from 1951?

Well, I put it back together and it runs. Difficult to start but I think that’s something to do with the linkage issues, but could also be something to do with that big spring and nylon bush not being in the correct place? I have the bush against the vane arm in the last pic with the spring around the spigot inside the magneto. It ran for about 5 mins, and actually dug a little hole. Then stalled and was a bugger to restart. Do you know what carb kit / gasket set I need by any chance? It’s a lovely little machine and I think will come in quite handy when up and running properly.

Hi wristpin, thanks for replying. Took it apart again this morning to take some pics as requested. I think it is an aspera engine. It’s the spring etc that goes on the magneto that is confusing me the most. The spring is on the last photos. In my head it seems to make sense for it to be located in the underside of the magneto with the white nylon bush thing pushing against the throttle rod spring thing in the last photo. I’m fact you can see where something has been rubbing
